+/**
+ * @ngdoc function
+ * @name angular.module.ng.$compile
+ * @function
+ *
+ * @description
+ * Compiles a piece of HTML string or DOM into a template and produces a template function, which
+ * can then be used to link {@link angular.module.ng.$rootScope.Scope scope} and the template together.
+ *
+ * The compilation is a process of walking the DOM tree and trying to match DOM elements to
+ * {@link angular.module.ng.$compileProvider.directive directives}. For each match it
+ * executes corresponding template function and collects the
+ * instance functions into a single template function which is then returned.
+ *
+ * The template function can then be used once to produce the view or as it is the case with
+ * {@link angular.module.ng.$compileProvider.directive.ng-repeat repeater} many-times, in which
+ * case each call results in a view that is a DOM clone of the original template.
+ *

+
+ *
+ *
+ * @param {string|DOMElement} element Element or HTML string to compile into a template function.
+ * @param {function(angular.Scope[, cloneAttachFn]} transclude function available to directives.
+ * @param {number} maxPriority only apply directives lower then given priority (Only effects the
+ *                 root element(s), not their children)
+ * @returns {function(scope[, cloneAttachFn])} a link function which is used to bind template
+ * (a DOM element/tree) to a scope. Where:
+ *
+ *  * `scope` - A {@link angular.module.ng.$rootScope.Scope Scope} to bind to.
+ *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
+ *               `template` and call the `cloneAttachFn` function allowing the caller to attach the
+ *               cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
+ *               called as: <br> `cloneAttachFn(clonedElement, scope)` where:
+ *
+ *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
+ *      * `scope` - is the current scope with which the linking function is working with.
+ *
+ * Calling the linking function returns the element of the template. It is either the original element
+ * passed in, or the clone of the element if the `cloneAttachFn` is provided.
+ *
+ * After linking the view is not updateh until after a call to $digest which typically is done by
+ * Angular automatically.
+ *
+ * If you need access to the bound view, there are two ways to do it:
+ *
+ * - If you are not asking the linking function to clone the template, create the DOM element(s)
+ *   before you send them to the compiler and keep this reference around.
+ *   <pre>
+ *     var element = $compile('<p>{{total}}</p>')(scope);
+ *   </pre>
+ *
+ * - if on the other hand, you need the element to be cloned, the view reference from the original
+ *   example would not point to the clone, but rather to the original template that was cloned. In
+ *   this case, you can access the clone via the cloneAttachFn:
+ *   <pre>
+ *     var templateHTML = angular.element('<p>{{total}}</p>'),
+ *         scope = ....;
+ *
+ *     var clonedElement = $compile(templateHTML)(scope, function(clonedElement, scope) {
+ *       //attach the clone to DOM document at the right place
+ *     });
+ *
+ *     //now we have reference to the cloned DOM via `clone`
+ *   </pre>
+ *
+ *
+ * For information on how the compiler works, see the
+ * {@link guide/dev_guide.compiler Angular HTML Compiler} section of the Developer Guide.

+ * @name angular.module.ng.$compileProvider.directive.form
+ * @restrict E
+ *
+ * @description
+ * Directive that instantiates
+ * {@link angular.module.ng.$compileProvider.directive.form.FormController FormController}.
+ *
+ * If `name` attribute is specified, the form controller is published onto the current scope under
+ * this name.
+ *
+ * # Alias: {@link angular.module.ng.$compileProvider.directive.ng-form `ng-form`}
+ *
+ * In angular forms can be nested. This means that the outer form is valid when all of the child
+ * forms are valid as well. However browsers do not allow nesting of `<form>` elements, for this
+ * reason angular provides {@link angular.module.ng.$compileProvider.directive.ng-form `ng-form`} alias
+ * which behaves identical to `<form>` but allows form nesting.
+ *
+ *
+ * # CSS classes
+ *  - `ng-valid` Is set if the form is valid.
+ *  - `ng-invalid` Is set if the form is invalid.
+ *  - `ng-pristine` Is set if the form is pristine.
+ *  - `ng-dirty` Is set if the form is dirty.
+ *
+ *
+ * # Submitting a form and preventing default action
+ *
+ * Since the role of forms in client-side Angular applications is different than in classical
+ * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
+ * page reload that sends the data to the server. Instead some javascript logic should be triggered
+ * to handle the form submission in application specific way.
+ *
+ * For this reason, Angular prevents the default action (form submission to the server) unless the
+ * `<form>` element has an `action` attribute specified.
+ *
+ * You can use one of the following two ways to specify what javascript method should be called when
+ * a form is submitted:
+ *
+ * - ng-submit on the form element (add link to ng-submit)
+ * - ng-click on the first button or input field of type submit (input[type=submit])
+ *
+ * To prevent double execution of the handler, use only one of ng-submit or ng-click. This is
+ * because of the following form submission rules coming from the html spec:
+ *
+ * - If a form has only one input field then hitting enter in this field triggers form submit
+ * (`ng-submit`)
+ * - if a form has has 2+ input fields and no buttons or input[type=submit] then hitting enter
+ * doesn't trigger submit
+ * - if a form has one or more input fields and one or more buttons or input[type=submit] then
+ * hitting enter in any of the input fields will trigger the click handler on the *first* button or
+ * input[type=submit] (`ng-click`) *and* a submit handler on the enclosing form (`ng-submit`)
+ *
+ * @param {string=} name Name of the form. If specified, the form controller will be published into
+ *                       related scope, under this name.

+ * @description
+ * Is directive that tells Angular to do two-way data binding. It works together with `input`,
+ * `select`, `textarea`. You can easily write your own directives to use `ng-model` as well.
+ *
+ * `ng-model` is responsible for:
+ *
+ * - binding the view into the model, which other directives such as `input`, `textarea` or `select`
+ *   require,
+ * - providing validation behavior (i.e. required, number, email, url),
+ * - keeping state of the control (valid/invalid, dirty/pristine, validation errors),
+ * - setting related css class onto the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`),
+ * - register the control with parent {@link angular.module.ng.$compileProvider.directive.form form}.
+ *
+ * For basic examples, how to use `ng-model`, see:
+ *
+ *  - {@link angular.module.ng.$compileProvider.directive.input input}
+ *    - {@link angular.module.ng.$compileProvider.directive.input.text text}
+ *    - {@link angular.module.ng.$compileProvider.directive.input.checkbox checkbox}

+ * expression changes.
+ *
+ * Typically, you don't use `ng-bind` directly, but instead you use the double curly markup like

+ * `<span ng-bind="expression"></span>` when the template is compiled.

+ * @element ANY
+ * @param {expression} ng-bind {@link guide/dev_guide.expressions Expression} to evaluate.
+ *
+ * @example
+ * Enter a name in the Live Preview text box; the greeting below the text box changes instantly.

+ * @ngdoc directive
+ * @name angular.module.ng.$compileProvider.directive.ng-cloak
+ *
+ * @description
+ * The `ng-cloak` directive is used to prevent the Angular html template from being briefly
+ * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
+ * directive to avoid the undesirable flicker effect caused by the html template display.
+ *
+ * The directive can be applied to the `<body>` element, but typically a fine-grained application is
+ * prefered in order to benefit from progressive rendering of the browser view.
+ *
+ * `ng-cloak` works in cooperation with a css rule that is embedded within `angular.js` and
+ *  `angular.min.js` files. Following is the css rule:
+ *
+ * <pre>
+ * [ng\:cloak], .ng-cloak {
+ *   display: none;
+ * }
+ * </pre>
+ *
+ * When this css rule is loaded by the browser, all html elements (including their children) that
+ * are tagged with the `ng-cloak` directive are hidden. When Angular comes across this directive
+ * during the compilation of the template it deletes the `ng-cloak` element attribute, which
+ * makes the compiled element visible.
+ *
+ * For the best result, `angular.js` script must be loaded in the head section of the html file;
+ * alternatively, the css rule (above) must be included in the external stylesheet of the
+ * application.
+ *
+ * Legacy browsers, like IE7, do not provide attribute selector support (added in CSS 2.1) so they
+ * cannot match the `[ng\:cloak]` selector. To work around this limitation, you must add the css
+ * class `ng-cloak` in addition to `ng-cloak` directive as shown in the example below.
+ *
+ * @element ANY
+ *
+ * @example
+   <doc:example>

+/**
+ * @ngdoc directive
+ * @name angular.module.ng.$compileProvider.directive.ng-controller
+ *
+ * @description
+ * The `ng-controller` directive assigns behavior to a scope. This is a key aspect of how angular
+ * supports the principles behind the Model-View-Controller design pattern.
+ *
+ * MVC components in angular:
+ *
+ * * Model — The Model is data in scope properties; scopes are attached to the DOM.
+ * * View — The template (HTML with data bindings) is rendered into the View.
+ * * Controller — The `ng-controller` directive specifies a Controller class; the class has
+ *   methods that typically express the business logic behind the application.
+ *
+ * Note that an alternative way to define controllers is via the `{@link angular.module.ng.$route}`
+ * service.
+ *
+ * @element ANY
+ * @scope
+ * @param {expression} ng-controller Name of a globally accessible constructor function or an
+ *     {@link guide/dev_guide.expressions expression} that on the current scope evaluates to a
+ *     constructor function.
+ *
+ * @example
+ * Here is a simple form for editing user contact information. Adding, removing, clearing, and
+ * greeting are methods declared on the controller (see source tab). These methods can
+ * easily be called from the angular markup. Notice that the scope becomes the `this` for the
+ * controller's instance. This allows for easy access to the view data from the controller. Also
+ * notice that any changes to the data are automatically reflected in the View without the need
+ * for a manual update.

+/**
+ * @ngdoc directive
+ * @name angular.module.ng.$compileProvider.directive.ng-pluralize
+ * @restrict EA
+ *
+ * @description
+ * # Overview
+ * ng-pluralize is a directive that displays messages according to en-US localization rules.
+ * These rules are bundled with angular.js and the rules can be overridden
+ * (see {@link guide/dev_guide.i18n Angular i18n} dev guide). You configure ng-pluralize by
+ * specifying the mappings between
+ * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
+ * plural categories} and the strings to be displayed.
+ *
+ * # Plural categories and explicit number rules
+ * There are two
+ * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
+ * plural categories} in Angular's default en-US locale: "one" and "other".
+ *
+ * While a pural category may match many numbers (for example, in en-US locale, "other" can match
+ * any number that is not 1), an explicit number rule can only match one number. For example, the
+ * explicit number rule for "3" matches the number 3. You will see the use of plural categories
+ * and explicit number rules throughout later parts of this documentation.
+ *
+ * # Configuring ng-pluralize
+ * You configure ng-pluralize by providing 2 attributes: `count` and `when`.
+ * You can also provide an optional attribute, `offset`.
+ *
+ * The value of the `count` attribute can be either a string or an {@link guide/dev_guide.expressions
+ * Angular expression}; these are evaluated on the current scope for its binded value.
+ *
+ * The `when` attribute specifies the mappings between plural categories and the actual
+ * string to be displayed. The value of the attribute should be a JSON object so that Angular
+ * can interpret it correctly.
+ *
+ * The following example shows how to configure ng-pluralize:
+ *
+ * <pre>
+ * <ng-pluralize count="personCount"
+                 when="{'0': 'Nobody is viewing.',
+ *                      'one': '1 person is viewing.',
+ *                      'other': '{} people are viewing.'}">
+ * </ng-pluralize>
+ *</pre>
+ *
+ * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
+ * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
+ * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
+ * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
+ * show "a dozen people are viewing".
+ *
+ * You can use a set of closed braces(`{}`) as a placeholder for the number that you want substituted
+ * into pluralized strings. In the previous example, Angular will replace `{}` with
+ * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
+ * for <span ng-non-bindable>{{numberExpression}}</span>.
+ *
+ * # Configuring ng-pluralize with offset
+ * The `offset` attribute allows further customization of pluralized text, which can result in
+ * a better user experience. For example, instead of the message "4 people are viewing this document",
+ * you might display "John, Kate and 2 others are viewing this document".
+ * The offset attribute allows you to offset a number by any desired value.
+ * Let's take a look at an example:
+ *
+ * <pre>
+ * <ng-pluralize count="personCount" offset=2
+ *               when="{'0': 'Nobody is viewing.',
+ *                      '1': '{{person1}} is viewing.',
+ *                      '2': '{{person1}} and {{person2}} are viewing.',
+ *                      'one': '{{person1}}, {{person2}} and one other person are viewing.',
+ *                      'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
+ * </ng-pluralize>
+ * </pre>
+ *
+ * Notice that we are still using two plural categories(one, other), but we added
+ * three explicit number rules 0, 1 and 2.
+ * When one person, perhaps John, views the document, "John is viewing" will be shown.
+ * When three people view the document, no explicit number rule is found, so
+ * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
+ * In this case, plural category 'one' is matched and "John, Marry and one other person are viewing"
+ * is shown.
+ *
+ * Note that when you specify offsets, you must provide explicit number rules for
+ * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
+ * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
+ * plural categories "one" and "other".
+ *
+ * @param {string|expression} count The variable to be bounded to.
+ * @param {string} when The mapping between plural category to its correspoding strings.
+ * @param {number=} offset Offset to deduct from the total number.
+ *
+ * @example
+    <doc:example>
+      <doc:source>
+        <script>
+          function Ctrl($scope) {
+            $scope.person1 = 'Igor';
+            $scope.person2 = 'Misko';
+            $scope.personCount = 1;
+          }
+        </script>
+        <div ng-controller="Ctrl">

+          Number of People:<input type="text" ng-model="personCount" value="1" /><br/>

+/**
+ * @ngdoc directive
+ * @name angular.module.ng.$compileProvider.directive.ng-repeat
+ *
+ * @description
+ * The `ng-repeat` directive instantiates a template once per item from a collection. Each template
+ * instance gets its own scope, where the given loop variable is set to the current collection item,
+ * and `$index` is set to the item index or key.
+ *
+ * Special properties are exposed on the local scope of each template instance, including:
+ *
+ *   * `$index` – `{number}` – iterator offset of the repeated element (0..length-1)
+ *   * `$position` – `{string}` – position of the repeated element in the iterator. One of:
+ *        * `'first'`,
+ *        * `'middle'`
+ *        * `'last'`
+ *
+ *
+ * @element ANY
+ * @scope
+ * @priority 1000
+ * @param {repeat_expression} ng-repeat The expression indicating how to enumerate a collection. Two
+ *   formats are currently supported:
+ *
+ *   * `variable in expression` – where variable is the user defined loop variable and `expression`
+ *     is a scope expression giving the collection to enumerate.
+ *
+ *     For example: `track in cd.tracks`.
+ *
+ *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
+ *     and `expression` is the scope expression giving the collection to enumerate.
+ *
+ *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
+ *
+ * @example
+ * This example initializes the scope to a list of names and
+ * then uses `ng-repeat` to display every person:
+    <doc:example>
+      <doc:source>
+        <div ng-init="friends = [{name:'John', age:25}, {name:'Mary', age:28}]">
+          I have {{friends.length}} friends. They are:
+          <ul>
+            <li ng-repeat="friend in friends">
+              [{{$index + 1}}] {{friend.name}} who is {{friend.age}} years old.
+            </li>
+          </ul>

+ *
+ * # `ng-options`
+ *
+ * Optionally `ng-options` attribute can be used to dynamically generate a list of `<option>`
+ * elements for a `<select>` element using an array or an object obtained by evaluating the
+ * `ng-options` expression.
+ *˝˝
+ * When an item in the select menu is select, the value of array element or object property
+ * represented by the selected option will be bound to the model identified by the `ng-model` attribute
+ * of the parent select element.
+ *
+ * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
+ * be nested into the `<select>` element. This element will then represent `null` or "not selected"
+ * option. See example below for demonstration.
+ *
+ * Note: `ng-options` provides iterator facility for `<option>` element which must be used instead
+ * of {@link angular.module.ng.$compileProvider.directive.ng-repeat ng-repeat}. `ng-repeat` is not suitable for use with
+ * `<option>` element because of the following reasons:
+ *
+ *   * value attribute of the option element that we need to bind to requires a string, but the
+ *     source of data for the iteration might be in a form of array containing objects instead of
+ *     strings
+ *   * {@link angular.module.ng.$compileProvider.directive.ng-repeat ng-repeat} unrolls after the select binds causing
+ *     incorect rendering on most browsers.
+ *   * binding to a value not in list confuses most browsers.
+ *
+ * @param {string} name assignable expression to data-bind to.
+ * @param {string=} required The control is considered valid only if value is entered.
+ * @param {comprehension_expression=} ng-options in one of the following forms:
+ *
+ *   * for array data sources:
+ *     * `label` **`for`** `value` **`in`** `array`
+ *     * `select` **`as`** `label` **`for`** `value` **`in`** `array`
+ *     * `label`  **`group by`** `group` **`for`** `value` **`in`** `array`
+ *     * `select` **`as`** `label` **`group by`** `group` **`for`** `value` **`in`** `array`
+ *   * for object data sources:
+ *     * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
+ *     * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
+ *     * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`
+ *     * `select` **`as`** `label` **`group by`** `group`
+ *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
+ *
+ * Where:
+ *
+ *   * `array` / `object`: an expression which evaluates to an array / object to iterate over.
+ *   * `value`: local variable which will refer to each item in the `array` or each property value
+ *      of `object` during iteration.
+ *   * `key`: local variable which will refer to a property name in `object` during iteration.
+ *   * `label`: The result of this expression will be the label for `<option>` element. The
+ *     `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
+ *   * `select`: The result of this expression will be bound to the model of the parent `<select>`
+ *      element. If not specified, `select` expression will default to `value`.
+ *   * `group`: The result of this expression will be used to group options using the `<optgroup>`
+ *      DOM element.

+ * @ngdoc filter
+ * @name angular.module.ng.$filter.filter
+ * @function
+ *
+ * @description
+ * Selects a subset of items from `array` and returns it as a new array.
+ *
+ * Note: This function is used to augment the `Array` type in Angular expressions. See
+ * {@link angular.module.ng.$filter} for more information about Angular arrays.
+ *
+ * @param {Array} array The source array.
+ * @param {string|Object|function()} expression The predicate to be used for selecting items from
+ *   `array`.
+ *
+ *   Can be one of:
+ *
+ *   - `string`: Predicate that results in a substring match using the value of `expression`
+ *     string. All strings or objects with string properties in `array` that contain this string
+ *     will be returned. The predicate can be negated by prefixing the string with `!`.
+ *
+ *   - `Object`: A pattern object can be used to filter specific properties on objects contained
+ *     by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
+ *     which have property `name` containing "M" and property `phone` containing "1". A special
+ *     property name `$` can be used (as in `{$:"text"}`) to accept a match against any
+ *     property of the object. That's equivalent to the simple substring match with a `string`
+ *     as described above.
+ *
+ *   - `function`: A predicate function can be used to write arbitrary filters. The function is
+ *     called for each element of `array`. The final result is an array of those elements that
+ *     the predicate returned true for.
+ *
+ * @example

+ * @description
+ *   Formats `date` to a string based on the requested `format`.
+ *
+ *   `format` string can be composed of the following elements:
+ *
+ *   * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
+ *   * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
+ *   * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
+ *   * `'MMMM'`: Month in year (January-December)
+ *   * `'MMM'`: Month in year (Jan-Dec)
+ *   * `'MM'`: Month in year, padded (01-12)
+ *   * `'M'`: Month in year (1-12)
+ *   * `'dd'`: Day in month, padded (01-31)
+ *   * `'d'`: Day in month (1-31)
+ *   * `'EEEE'`: Day in Week,(Sunday-Saturday)
+ *   * `'EEE'`: Day in Week, (Sun-Sat)
+ *   * `'HH'`: Hour in day, padded (00-23)
+ *   * `'H'`: Hour in day (0-23)
+ *   * `'hh'`: Hour in am/pm, padded (01-12)
+ *   * `'h'`: Hour in am/pm, (1-12)
+ *   * `'mm'`: Minute in hour, padded (00-59)
+ *   * `'m'`: Minute in hour (0-59)
+ *   * `'ss'`: Second in minute, padded (00-59)
+ *   * `'s'`: Second in minute (0-59)
+ *   * `'a'`: am/pm marker
+ *   * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-1200)
+ *
+ *   `format` string can also be one of the following predefined
+ *   {@link guide/dev_guide.i18n localizable formats}:
+ *
+ *   * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
+ *     (e.g. Sep 3, 2010 12:05:08 pm)
+ *   * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US  locale (e.g. 9/3/10 12:05 pm)
+ *   * `'fullDate'`: equivalent to `'EEEE, MMMM d,y'` for en_US  locale
+ *     (e.g. Friday, September 3, 2010)
+ *   * `'longDate'`: equivalent to `'MMMM d, y'` for en_US  locale (e.g. September 3, 2010
+ *   * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US  locale (e.g. Sep 3, 2010)
+ *   * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
+ *   * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 pm)
+ *   * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 pm)
+ *
+ *   `format` string can contain literal values. These need to be quoted with single quotes (e.g.
+ *   `"h 'in the morning'"`). In order to output single quote, use two single quotes in a sequence
+ *   (e.g. `"h o''clock"`).
+ *
+ * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
+ *    number) or ISO 8601 extended datetime string (yyyy-MM-ddTHH:mm:ss.SSSZ).
+ * @param {string=} format Formatting rules (see Description). If not specified,
+ *    `mediumDate` is used.
+ * @returns {string} Formatted string or the input if input is not recognized as date/millis.

+     * {@link angular.module.ngMock.$httpBackend $httpBackend mock}.
+     *
+     * For a higher level of abstraction, please check out the {@link angular.module.ng.$resource
+     * $resource} service.
+     *
+     * The $http API is based on the {@link angular.module.ng.$q deferred/promise APIs} exposed by
+     * the $q service. While for simple usage patters this doesn't matter much, for advanced usage,
+     * it is important to familiarize yourself with these apis and guarantees they provide.
+     *
+     *
+     * # General usage
+     * The `$http` service is a function which takes a single argument — a configuration object —
+     * that is used to generate an http request and returns  a {@link angular.module.ng.$q promise}
+     * with two $http specific methods: `success` and `error`.
+     *
+     * <pre>
+     *   $http({method: 'GET', url: '/someUrl'}).
+     *     success(function(data, status, headers, config) {
+     *       // this callback will be called asynchronously
+     *       // when the response is available
+     *     }).
+     *     error(function(data, status, headers, config) {
+     *       // called asynchronously if an error occurs
+     *       // or server returns response with status
+     *       // code outside of the <200, 400) range
+     *     });
+     * </pre>
+     *
+     * Since the returned value of calling the $http function is a Promise object, you can also use
+     * the `then` method to register callbacks, and these callbacks will receive a single argument –
+     * an object representing the response. See the api signature and type info below for more
+     * details.
+     *
+     *
+     * # Shortcut methods
+     *
+     * Since all invocation of the $http service require definition of the http method and url and
+     * POST and PUT requests require response body/data to be provided as well, shortcut methods
+     * were created to simplify using the api:
+     *
+     * <pre>
+     *   $http.get('/someUrl').success(successCallback);
+     *   $http.post('/someUrl', data).success(successCallback);
+     * </pre>
+     *
+     * Complete list of shortcut methods:
+     *
+     * - {@link angular.module.ng.$http#get $http.get}
+     * - {@link angular.module.ng.$http#head $http.head}
+     * - {@link angular.module.ng.$http#post $http.post}
+     * - {@link angular.module.ng.$http#put $http.put}
+     * - {@link angular.module.ng.$http#delete $http.delete}
+     * - {@link angular.module.ng.$http#jsonp $http.jsonp}
+     *
+     *
+     * # Setting HTTP Headers
+     *
+     * The $http service will automatically add certain http headers to all requests. These defaults
+     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
+     * object, which currently contains this default configuration:
+     *
+     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
+     *   - `Accept: application/json, text/plain, * / *`
+     *   - `X-Requested-With: XMLHttpRequest`
+     * - `$httpProvider.defaults.headers.post`: (header defaults for HTTP POST requests)
+     *   - `Content-Type: application/json`
+     * - `$httpProvider.defaults.headers.put` (header defaults for HTTP PUT requests)
+     *   - `Content-Type: application/json`
+     *
+     * To add or overwrite these defaults, simply add or remove a property from this configuration
+     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
+     * with name equal to the lower-cased http method name, e.g.
+     * `$httpProvider.defaults.headers.get['My-Header']='value'`.
+     *
+     *
+     * # Transforming Requests and Responses
+     *
+     * Both requests and responses can be transformed using transform functions. By default, Angular
+     * applies these transformations:
+     *
+     * Request transformations:
+     *
+     * - if the `data` property of the request config object contains an object, serialize it into
+     *   JSON format.
+     *
+     * Response transformations:
+     *
+     *  - if XSRF prefix is detected, strip it (see Security Considerations section below)
+     *  - if json response is detected, deserialize it using a JSON parser
+     *
+     * To override these transformation locally, specify transform functions as `transformRequest`
+     * and/or `transformResponse` properties of the config object. To globally override the default
+     * transforms, override the `$httpProvider.defaults.transformRequest` and
+     * `$httpProvider.defaults.transformResponse` properties of the `$httpProvider`.
+     *
+     *
+     * # Caching
+     *
+     * To enable caching set the configuration property `cache` to `true`. When the cache is
+     * enabled, `$http` stores the response from the server in local cache. Next time the
+     * response is served from the cache without sending a request to the server.
+     *
+     * Note that even if the response is served from cache, delivery of the data is asynchronous in
+     * the same way that real requests are.
+     *
+     * If there are multiple GET requests for the same url that should be cached using the same
+     * cache, but the cache is not populated yet, only one request to the server will be made and
+     * the remaining requests will be fulfilled using the response for the first request.
+     *
+     *
+     * # Response interceptors
+     *
+     * Before you start creating interceptors, be sure to understand the
+     * {@link angular.module.ng.$q $q and deferred/promise APIs}.
+     *
+     * For purposes of global error handling, authentication or any kind of synchronous or
+     * asynchronous preprocessing of received responses, it is desirable to be able to intercept
+     * responses for http requests before they are handed over to the application code that
+     * initiated these requests. The response interceptors leverage the {@link angular.module.ng.$q
+     * promise apis} to fulfil this need for both synchronous and asynchronous preprocessing.
+     *
+     * The interceptors are service factories that are registered with the $httpProvider by
+     * adding them to the `$httpProvider.responseInterceptors` array. The factory is called and
+     * injected with dependencies (if specified) and returns the interceptor  — a function that
+     * takes a {@link angular.module.ng.$q promise} and returns the original or a new promise.
+     *
+     * <pre>
+     *   // register the interceptor as a service
+     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
+     *     return function(promise) {
+     *       return promise.then(function(response) {
+     *         // do something on success
+     *       }, function(response) {
+     *         // do something on error
+     *         if (canRecover(response)) {
+     *           return responseOrNewPromise
+     *         }
+     *         return $q.reject(response);
+     *       });
+     *     }
+     *   });
+     *
+     *   $httpProvider.responseInterceptors.push('myHttpInterceptor');
+     *
+     *
+     *   // register the interceptor via an anonymous factory
+     *   $httpProvider.responseInterceptors.push(function($q, dependency1, dependency2) {
+     *     return function(promise) {
+     *       // same as above
+     *     }
+     *   });
+     * </pre>
+     *
+     *
+     * # Security Considerations
+     *
+     * When designing web applications, consider security threats from:
+     *
+     * - {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
+     *   JSON Vulnerability}
+     * - {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF}
+     *
+     * Both server and the client must cooperate in order to eliminate these threats. Angular comes
+     * pre-configured with strategies that address these issues, but for this to work backend server
+     * cooperation is required.
+     *
+     * ## JSON Vulnerability Protection
+     *
+     * A {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
+     * JSON Vulnerability} allows third party web-site to turn your JSON resource URL into
+     * {@link http://en.wikipedia.org/wiki/JSON#JSONP JSONP} request under some conditions. To
+     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
+     * Angular will automatically strip the prefix before processing it as JSON.
+     *
+     * For example if your server needs to return:
+     * <pre>
+     * ['one','two']
+     * </pre>
+     *
+     * which is vulnerable to attack, your server can return:
+     * <pre>
+     * )]}',
+     * ['one','two']
+     * </pre>
+     *
+     * Angular will strip the prefix, before processing the JSON.
+     *
+     *
+     * ## Cross Site Request Forgery (XSRF) Protection
+     *
+     * {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} is a technique by which
+     * an unauthorized site can gain your user's private data. Angular provides following mechanism
+     * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie
+     * called `XSRF-TOKEN` and sets it as the HTTP header `X-XSRF-TOKEN`. Since only JavaScript that
+     * runs on your domain could read the cookie, your server can be assured that the XHR came from
+     * JavaScript running on your domain.
+     *
+     * To take advantage of this, your server needs to set a token in a JavaScript readable session
+     * cookie called `XSRF-TOKEN` on first HTTP GET request. On subsequent non-GET requests the
+     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
+     * that only JavaScript running on your domain could have read the token. The token must be
+     * unique for each user and must be verifiable by the server (to prevent the JavaScript making
+     * up its own tokens). We recommend that the token is a digest of your site's authentication
+     * cookie with {@link http://en.wikipedia.org/wiki/Rainbow_table salt for added security}.
+     *
+     *
+     * @param {object} config Object describing the request to be made and how it should be
+     *    processed. The object has following properties:
+     *
+     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
+     *    - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
+     *    - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be turned to
+     *      `?key1=value1&key2=value2` after the url. If the value is not a string, it will be JSONified.
+     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
+     *    - **headers** – `{Object}` – Map of strings representing HTTP headers to send to the server.
+     *    - **transformRequest** – `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
+     *      transform function or an array of such functions. The transform function takes the http
+     *      request body and headers and returns its transformed (typically serialized) version.
+     *    - **transformResponse** – `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
+     *      transform function or an array of such functions. The transform function takes the http
+     *      response body and headers and returns its transformed (typically deserialized) version.
+     *    - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
+     *      GET request, otherwise if a cache instance built with
+     *      {@link angular.module.ng.$cacheFactory $cacheFactory}, this cache will be used for
+     *      caching.
+     *    - **timeout** – `{number}` – timeout in milliseconds.
+     *
+     * @returns {HttpPromise} Returns a {@link angular.module.ng.$q promise} object with the
+     *   standard `then` method and two http specific methods: `success` and `error`. The `then`
+     *   method takes two arguments a success and an error callback which will be called with a
+     *   response object. The `success` and `error` methods take a single argument - a function that
+     *   will be called when the request succeeds or fails respectively. The arguments passed into
+     *   these functions are destructured representation of the response object passed into the
+     *   `then` method. The response object has these properties:
+     *
+     *   - **data** – `{string|Object}` – The response body transformed with the transform functions.
+     *   - **status** – `{number}` – HTTP status code of the response.
+     *   - **headers** – `{function([headerName])}` – Header getter function.
+     *   - **config** – `{Object}` – The configuration object that was used to generate the request.
+     *
+     * @property {Array.<Object>} pendingRequests Array of config objects for currently pending
+     *   requests. This is primarily meant to be used for debugging purposes.

+/**
+ * @ngdoc service
+ * @name angular.module.ng.$q
+ * @requires $rootScope
+ *
+ * @description
+ * A promise/deferred implementation inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
+ *
+ * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
+ * interface for interacting with an object that represents the result of an action that is
+ * performed asynchronously, and may or may not be finished at any given point in time.
+ *
+ * From the perspective of dealing with error handling, deferred and promise apis are to
+ * asynchronous programing what `try`, `catch` and `throw` keywords are to synchronous programing.
+ *
+ * <pre>
+ *   // for the purpose of this example let's assume that variables `$q` and `scope` are
+ *   // available in the current lexical scope (they could have been injected or passed in).
+ *
+ *   function asyncGreet(name) {
+ *     var deferred = $q.defer();
+ *
+ *     setTimeout(function() {
+ *       // since this fn executes async in a future turn of the event loop, we need to wrap
+ *       // our code into an $apply call so that the model changes are properly observed.
+ *       scope.$apply(function() {
+ *         if (okToGreet(name)) {
+ *           deferred.resolve('Hello, ' + name + '!');
+ *         } else {
+ *           deferred.reject('Greeting ' + name + ' is not allowed.');
+ *         }
+ *       });
+ *     }, 1000);
+ *
+ *     return deferred.promise;
+ *   }
+ *
+ *   var promise = asyncGreet('Robin Hood');
+ *   promise.then(function(greeting) {
+ *     alert('Success: ' + greeting);
+ *   }, function(reason) {
+ *     alert('Failed: ' + reason);
+ *   );
+ * </pre>
+ *
+ * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
+ * comes in the way of
+ * [guarantees that promise and deferred apis make](https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md).
+ *
+ * Additionally the promise api allows for composition that is very hard to do with the
+ * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
+ * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
+ * section on serial or parallel joining of promises.
+ *
+ *
+ * # The Deferred API
+ *
+ * A new instance of deferred is constructed by calling `$q.defer()`.
+ *
+ * The purpose of the deferred object is to expose the associated Promise instance as well as apis
+ * that can be used for signaling the successful or unsuccessful completion of the task.
+ *
+ * **Methods**
+ *
+ * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
+ *   constructed via `$q.reject`, the promise will be rejected instead.
+ * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
+ *   resolving it with a rejection constructed via `$q.reject`.
+ *
+ * **Properties**
+ *
+ * - promise – `{Promise}` – promise object associated with this deferred.
+ *
+ *
+ * # The Promise API
+ *
+ * A new promise instance is created when a deferred instance is created and can be retrieved by
+ * calling `deferred.promise`.
+ *
+ * The purpose of the promise object is to allow for interested parties to get access to the result
+ * of the deferred task when it completes.
+ *
+ * **Methods**
+ *
+ * - `then(successCallback, errorCallback)` – regardless of when the promise was or will be resolved
+ *   or rejected calls one of the success or error callbacks asynchronously as soon as the result
+ *   is available. The callbacks are called with a single argument the result or rejection reason.
+ *
+ *   This method *returns a new promise* which is resolved or rejected via the return value of the
+ *   `successCallback` or `errorCallback`.
+ *
+ *
+ * # Chaining promises
+ *
+ * Because calling `then` api of a promise returns a new derived promise, it is easily possible
+ * to create a chain of promises:
+ *
+ * <pre>
+ *   promiseB = promiseA.then(function(result) {
+ *     return result + 1;
+ *   });
+ *
+ *   // promiseB will be resolved immediately after promiseA is resolved and it's value will be
+ *   // the result of promiseA incremented by 1
+ * </pre>
+ *
+ * It is possible to create chains of any length and since a promise can be resolved with another
+ * promise (which will defer its resolution further), it is possible to pause/defer resolution of
+ * the promises at any point in the chain. This makes it possible to implement powerful apis like
+ * $http's response interceptors.
+ *
+ *
+ * # Differences between Kris Kowal's Q and $q
+ *
+ *  There are three main differences:
+ *
+ * - $q is integrated with the {@link angular.module.ng.$rootScope.Scope} Scope model observation
+ *   mechanism in angular, which means faster propagation of resolution or rejection into your
+ *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
+ * - $q promises are recognized by the templating engine in angular, which means that in templates
+ *   you can treat promises attached to a scope as if they were the resulting values.
+ * - Q has many more features that $q, but that comes at a cost of bytes. $q is tiny, but contains
+ *   all the important functionality needed for common async tasks.

+ * @requires $http
+ *
+ * @description
+ * A factory which creates a resource object that lets you interact with
+ * [RESTful](http://en.wikipedia.org/wiki/Representational_State_Transfer) server-side data sources.
+ *
+ * The returned resource object has action methods which provide high-level behaviors without
+ * the need to interact with the low level {@link angular.module.ng.$http $http} service.
+ *
+ * @param {string} url A parameterized URL template with parameters prefixed by `:` as in
+ *   `/user/:username`.
+ *
+ * @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in
+ *   `actions` methods.
+ *
+ *   Each key value in the parameter object is first bound to url template if present and then any
+ *   excess keys are appended to the url search query after the `?`.
+ *
+ *   Given a template `/path/:verb` and parameter `{verb:'greet', salutation:'Hello'}` results in
+ *   URL `/path/greet?salutation=Hello`.
+ *
+ *   If the parameter value is prefixed with `@` then the value of that parameter is extracted from
+ *   the data object (useful for non-GET operations).
+ *
+ * @param {Object.<Object>=} actions Hash with declaration of custom action that should extend the
+ *   default set of resource actions. The declaration should be created in the following format:
+ *
+ *       {action1: {method:?, params:?, isArray:?},
+ *        action2: {method:?, params:?, isArray:?},
+ *        ...}
+ *
+ *   Where:
+ *
+ *   - `action` – {string} – The name of action. This name becomes the name of the method on your
+ *     resource object.
+ *   - `method` – {string} – HTTP request method. Valid methods are: `GET`, `POST`, `PUT`, `DELETE`,
+ *     and `JSONP`
+ *   - `params` – {object=} – Optional set of pre-bound parameters for this action.
+ *   - isArray – {boolean=} – If true then the returned object for this action is an array, see
+ *     `returns` section.
+ *
+ * @returns {Object} A resource "class" object with methods for the default set of resource actions
+ *   optionally extended with custom `actions`. The default set contains these actions:
+ *
+ *       { 'get':    {method:'GET'},
+ *         'save':   {method:'POST'},
+ *         'query':  {method:'GET', isArray:true},
+ *         'remove': {method:'DELETE'},
+ *         'delete': {method:'DELETE'} };
+ *
+ *   Calling these methods invoke an {@link angular.module.ng.$http} with the specified http method,
+ *   destination and parameters. When the data is returned from the server then the object is an
+ *   instance of the resource class `save`, `remove` and `delete` actions are available on it as
+ *   methods with the `$` prefix. This allows you to easily perform CRUD operations (create, read,
+ *   update, delete) on server-side data like this:
+ *   <pre>
+        var User = $resource('/user/:userId', {userId:'@id'});
+        var user = User.get({userId:123}, function() {
+          user.abc = true;
+          user.$save();
+        });
+     </pre>
+ *
+ *   It is important to realize that invoking a $resource object method immediately returns an
+ *   empty reference (object or array depending on `isArray`). Once the data is returned from the
+ *   server the existing reference is populated with the actual data. This is a useful trick since
+ *   usually the resource is assigned to a model which is then rendered by the view. Having an empty
+ *   object results in no rendering, once the data arrives from the server then the object is
+ *   populated with the data and the view automatically re-renders itself showing the new data. This
+ *   means that in most case one never has to write a callback function for the action methods.
+ *
+ *   The action methods on the class object or instance object can be invoked with the following
+ *   parameters:
+ *
+ *   - HTTP GET "class" actions: `Resource.action([parameters], [success], [error])`
+ *   - non-GET "class" actions: `Resource.action([parameters], postData, [success], [error])`
+ *   - non-GET instance actions:  `instance.$action([parameters], [success], [error])`
+ *
+ *
+ * @example
+ *
+ * # Credit card resource
+ *
+ * <pre>
+     // Define CreditCard class
+     var CreditCard = $resource('/user/:userId/card/:cardId',
+      {userId:123, cardId:'@id'}, {
+       charge: {method:'POST', params:{charge:true}}
+      });
+
+     // We can retrieve a collection from the server
+     var cards = CreditCard.query();
+     // GET: /user/123/card
+     // server returns: [ {id:456, number:'1234', name:'Smith'} ];
+

+ * The object returned from this function execution is a resource "class" which has "static" method
+ * for each action in the definition.
+ *
+ * Calling these methods invoke `$http` on the `url` template with the given `method` and `params`.
+ * When the data is returned from the server then the object is an instance of the resource type and
+ * all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD
+ * operations (create, read, update, delete) on server-side data.
+
+   <pre>
+     var User = $resource('/user/:userId', {userId:'@id'});
+     var user = User.get({userId:123}, function() {
+       user.abc = true;
+       user.$save();
+     });
+   </pre>
+ *
+ *     It's worth noting that the success callback for `get`, `query` and other method gets passed
+ *     in the response that came from the server as well as $http header getter function, so one
+ *     could rewrite the above example and get access to http headers as:
+ *
+   <pre>
+     var User = $resource('/user/:userId', {userId:'@id'});
+     User.get({userId:123}, function(u, getResponseHeaders){
+       u.abc = true;
+       u.$save(function(u, putResponseHeaders) {
+         //u => saved user object
+         //putResponseHeaders => $http header getter

+/**
+ * DESIGN NOTES
+ *
+ * The design decisions behind the scope ware heavily favored for speed and memory consumption.
+ *
+ * The typical use of scope is to watch the expressions, which most of the time return the same
+ * value as last time so we optimize the operation.
+ *
+ * Closures construction is expensive from speed as well as memory:
+ *   - no closures, instead ups prototypical inheritance for API
+ *   - Internal state needs to be stored on scope directly, which means that private state is
+ *     exposed as $$____ properties
+ *
+ * Loop operations are optimized by using while(count--) { ... }
+ *   - this means that in order to keep the same order of execution as addition we have to add
+ *     items to the array at the begging (shift) instead of at the end (push)
+ *
+ * Child scopes are created and removed often
+ *   - Using array would be slow since inserts in meddle are expensive so we use linked list
+ *
+ * There are few watches then a lot of observers. This is why you don't want the observer to be
+ * implemented in the same way as watch. Watch requires return of initialization function which
+ * are expensive to construct.

+       *   should return the value which will be watched. (Since {@link angular.module.ng.$rootScope.Scope#$digest $digest()}
+       *   reruns when it detects changes the `watchExpression` can execute multiple times per
+       *   {@link angular.module.ng.$rootScope.Scope#$digest $digest()} and should be idempotent.)
+       * - The `listener` is called only when the value from the current `watchExpression` and the
+       *   previous call to `watchExpression' are not equal (with the exception of the initial run
+       *   see below). The inequality is determined according to
+       *   {@link angular.equals} function. To save the value of the object for later comparison
+       *   {@link angular.copy} function is used. It also means that watching complex options will
+       *   have adverse memory and performance implications.
+       * - The watch `listener` may change the model, which may trigger other `listener`s to fire. This
+       *   is achieved by rerunning the watchers until no changes are detected. The rerun iteration
+       *   limit is 100 to prevent infinity loop deadlock.
+       *
+       *
+       * If you want to be notified whenever {@link angular.module.ng.$rootScope.Scope#$digest $digest} is called,
+       * you can register an `watchExpression` function with no `listener`. (Since `watchExpression`,
+       * can execute multiple times per {@link angular.module.ng.$rootScope.Scope#$digest $digest} cycle when a change is
+       * detected, be prepared for multiple calls to your listener.)
+       *
+       * After a watcher is registered with the scope, the `listener` fn is called asynchronously
+       * (via {@link angular.module.ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
+       * watcher. In rare cases, this is undesirable because the listener is called when the result
+       * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
+       * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
+       * listener was called due to initialization.
+       *

+ * @ngdoc object
+ * @name angular.module.ng.$routeParams
+ * @requires $route
+ *
+ * @description
+ * Current set of route parameters. The route parameters are a combination of the
+ * {@link angular.module.ng.$location $location} `search()`, and `path()`. The `path` parameters
+ * are extracted when the {@link angular.module.ng.$route $route} path is matched.
+ *
+ * In case of parameter name collision, `path` params take precedence over `search` params.
+ *
+ * The service guarantees that the identity of the `$routeParams` object will remain unchanged
+ * (but its properties will likely change) even when a route change occurs.
+ *
+ * @example
+ * <pre>
+ *  // Given:
+ *  // URL: http://server.com/index.html#/Chapter/1/Section/2?search=moby
+ *  // Route: /Chapter/:chapterId/Section/:sectionId
+ *  //
+ *  // Then
+ *  $routeParams ==> {chapterId:1, sectionId:2, search:'moby'}

+ * @description
+ *   The input is sanitized by parsing the html into tokens. All safe tokens (from a whitelist) are
+ *   then serialized back to properly escaped html string. This means that no unsafe input can make
+ *   it into the returned string, however, since our parser is more strict than a typical browser
+ *   parser, it's possible that some obscure input, which would be recognized as valid HTML by a
+ *   browser, won't make it through the sanitizer.
+ *
+ * @param {string} html Html input.
+ * @returns {string} Sanitized html.
