    /**
     * @ngdoc overview
     * @name angular.directive
     * @namespace Namespace for all directives.
     * @description
     * A directive is an XML attribute that you can use in an existing HTML 
     * element type or in a DOM element type that you create using 
     * `angular.widget`, to modify that element's properties. You can use 
     * any number of directives per element.
     * 
     * For example, you can add the ng:bind directive as an attribute of an 
     * HTML span element, as in `<span ng:bind="1+2"></span>`. 
     * How does this work? The compiler passes the attribute value `1+2` 
     * to the ng:bind extension, which in turn tells the Scope to watch
     * that expression and report changes. On any change it sets the span
     * text to the expression value.
     * 
     * Here's how to define ng:bind:
     * <pre>
        angular.directive('ng:bind', function(expression, compiledElement) {
          var compiler = this;
          return function(linkElement) {
            var currentScope = this;
            currentScope.$watch(expression, function(value) {
              linkElement.text(value);
            });
          };
        });
     * </pre>
     * 
     * ## Directive vs. Attribute Widget
     * Both attribute widgets and directives can compile a DOM element 
     * attribute. So why have two different ways to do the same thing? 
     * The answer is that order matters, but you have no control over 
     * the order in which attributes are read. To solve this we
     * apply attribute widget before the directive. 
     * 
     * For example, consider this piece of HTML, which uses the 
     * directives `ng:repeat`, `ng:init`, and `ng:bind`:
     * <pre>
        <ul ng:init="people=['mike', 'mary']">
          <li ng:repeat="person in people" ng:init="a=a+1" ng:bind="person"></li>
        </ul>
     * </pre>
     * 
     * Notice that the order of execution matters here. We need to 
     * execute ng:repeat before we run the `ng:init` and `ng:bind` 
     * on the `<li/>;`. This is because we want to run the 
     * `ng:init="a=a+1` and `ng:bind="person"` once for each 
     * person in people. We could not have used directive to 
     * create this template because attributes are read in an 
     * unspecified order and there is no way of guaranteeing 
     * that the repeater attribute would execute first. Using 
     * the `ng:repeat` attribute directive ensures that we can 
     * transform the DOM element into a template.
     * 
     * Widgets run before directives. Widgets are expected to 
     * manipulate the DOM whereas directives are not expected 
     * to manipulate the DOM, and they run last.

     * @name angular.widget
     * @namespace Namespace for all widgets.
     * @description
     * # Overview
     * Widgets allow you to create DOM elements that the browser doesn't 
     * already understand. You create the widget in your namespace and 
     * assign it behavior. You can only bind one widget per DOM element 
     * (unlike directives, in which you can use any number per DOM 
     * element). Widgets are expected to manipulate the DOM tree by 
     * adding new elements whereas directives are expected to only modify
     * element properties.
     * 
     * Widgets come in two flavors: element and attribute.
     * 
     * # Element Widget
     * Let's say we would like to create a new element type in the 
     * namespace `my` that can watch an expression and alert() the user 
     * with each new value.
     * 
     * <pre>
     * &lt;my:watch exp="name"/&gt;
     * </pre>
     * 
     * You can implement `my:watch` like this:
     * <pre>
     * angular.widget('my:watch', function(compileElement) {
     *   var compiler = this;
     *   var exp = compileElement.attr('exp');
     *   return function(linkElement) {
     *     var currentScope = this;
     *     currentScope.$watch(exp, function(value){
     *       alert(value);
     *     }};
     *   };
     * });
     * </pre>
     * 
     * # Attribute Widget
     * Let's implement the same widget, but this time as an attribute 
     * that can be added to any existing DOM element.
     * <pre>
     * &lt;div my-watch="name"&gt;text&lt;/div&gt;
     * </pre>
     * You can implement `my:watch` attribute like this:
     * <pre>
     * angular.widget('@my:watch', function(expression, compileElement) {
     *   var compiler = this;
     *   return function(linkElement) {
     *     var currentScope = this;
     *     currentScope.$watch(expression, function(value){
     *       alert(value);
     *     });
     *   };
     * });
     * </pre>
     * 
     * @example
     * <script>
     *   angular.widget('my:time', function(compileElement){
     *     compileElement.css('display', 'block');
     *     return function(linkElement){
     *       function update(){
     *         linkElement.text('Current time is: ' + new Date());
     *         setTimeout(update, 1000);
     *       }
     *       update();
     *     };
     *   });

     * # Overview
     * Validators are a standard way to check the user input against a specific criteria. For 
     * example, you might need to check that an input field contains a well-formed phone number.
     * 
     * # Syntax
     * Attach a validator on user input widgets using the `ng:validate` attribute.
     * 
     * <doc:example>
     *   <doc:source>
     *     Change me: &lt;input type="text" name="number" ng:validate="integer" value="123"&gt;

     *       expect(element('input[name=number]').attr('class')).
     *          toMatch(/ng-validation-error/);
     *     });
     *   </doc:scenario>
     * </doc:example>
     * 
     *
     * # Writing your own Validators
     * Writing your own validator is easy. To make a function available as a 
     * validator, just define the JavaScript function on the `angular.validator` 
     * object. <angular/> passes in the input to validate as the first argument 
     * to your function. Any additional validator arguments are passed in as 
     * additional arguments to your function.
     * 
     * You can use these variables in the function:
     *
     * * `this` — The current scope.
     * * `this.$element` — The DOM element containing the binding. This allows the filter to manipulate
     *   the DOM in addition to transforming the input.
     *   
     * In this example we have written a upsTrackingNo validator. 
     * It marks the input text "valid" only when the user enters a well-formed 
     * UPS tracking number.
     *
     * @css ng-validation-error
     *   When validation fails, this css class is applied to the binding, making its borders red by
     *   default.
     * 
     * @example
     * <script>
     *  angular.validator('upsTrackingNo', function(input, format) {
     *    var regexp = new RegExp("^" + format.replace(/9/g, '\\d') + "$");
     *    return input.match(regexp)?"":"The format must match " + format;
     *  });
     * </script>
     * <input type="text" name="trackNo" size="40"
     *       ng:validate="upsTrackingNo:'1Z 999 999 99 9999 999 9'" 
     *       value="1Z 123 456 78 9012 345 6"/>
     *
     * @scenario
     * it('should validate correct UPS tracking number', function() {
     *   expect(element('input[name=trackNo]').attr('class')).
     *      not().toMatch(/ng-validation-error/);
     * });
     *
     * it('should not validate in correct UPS tracking number', function() {
     *   input('trackNo').enter('foo');
     *   expect(element('input[name=trackNo]').attr('class')).

     * @name angular.filter
     * @namespace Namespace for all filters.
     * @description
     * # Overview
     * Filters are a standard way to format your data for display to the user. For example, you
     * might have the number 1234.5678 and would like to display it as US currency: $1,234.57.
     * Filters allow you to do just that. In addition to transforming the data, filters also modify
     * the DOM. This allows the filters to for example apply css styles to the filtered output if
     * certain conditions were met.
     *
     *
     * # Standard Filters
     *
     * The Angular framework provides a standard set of filters for common operations, including:
     * {@link angular.filter.currency}, {@link angular.filter.json}, {@link angular.filter.number},
     * and {@link angular.filter.html}. You can also add your own filters.
     *
     *
     * # Syntax
     *
     * Filters can be part of any {@link angular.scope} evaluation but are typically used with
     * {{bindings}}. Filters typically transform the data to a new data type, formating the data in
     * the process. Filters can be chained and take optional arguments. Here are few examples:
     *
     * * No filter: {{1234.5678}} => 1234.5678
     * * Number filter: {{1234.5678|number}} => 1,234.57. Notice the “,” and rounding to two
     *   significant digits.
     * * Filter with arguments: {{1234.5678|number:5}} => 1,234.56780. Filters can take optional
     *   arguments, separated by colons in a binding. To number, the argument “5” requests 5 digits
     *   to the right of the decimal point.
     *
     *
     * # Writing your own Filters
     *
     * Writing your own filter is very easy: just define a JavaScript function on `angular.filter`.
     * The framework passes in the input value as the first argument to your function. Any filter
     * arguments are passed in as additional function arguments.
     *
     * You can use these variables in the function:
     *
     * * `this` — The current scope.
     * * `this.$element` — The DOM element containing the binding. This allows the filter to manipulate
     *   the DOM in addition to transforming the input.
     *
     *
     * @exampleDescription
     *  The following example filter reverses a text string. In addition, it conditionally makes the
     *  text upper-case (to demonstrate optional arguments) and assigns color (to demonstrate DOM
     *  modification).
     *
     * @example
         <script type="text/javascript">
           angular.filter('reverse', function(input, uppercase, color) {
             var out = "";
             for (var i = 0; i < input.length; i++) {
               out = input.charAt(i) + out;
             }
             if (uppercase) {
               out = out.toUpperCase();
             }
             if (color) {
               this.$element.css('color', color);
             }
             return out;
           });
         </script>

         <input name="text" type="text" value="hello" /><br>
         No filter: {{text}}<br>
         Reverse: {{text|reverse}}<br>

/**
 * @ngdoc directive
 * @name angular.directive.ng:autobind
 * @element script
 *
 * @description
 * This section explains how to bootstrap your application to 
 * the <angular/> environment using either the 
 * `angular-x.x.x.js` or `angular-x.x.x.min.js` script.
 * 
 * ## The bootstrap code
 * Note that there are two versions of the bootstrap code that you can use:
 * 
 * * `angular-x.x.x.js` - this file is unobfuscated, uncompressed, and thus 
 *     human-readable. Note that despite the name of the file, there is 
 *     no additional functionality built in to help you debug your 
 *     application; it has the prefix debug because you can read 
 *     the source code.
 * * `angular-x.x.x.min.js` - this is a compressed and obfuscated version 
 *     of `angular-x.x.x.js`. You might want to use this version if you 
 *     want to load a smaller but functionally equivalent version of the 
 *     code in your application. Note: this minified version was created 
 *     using the Closure Compiler.
 *     
 * 
 * ## Auto bind using: <tt>ng:autobind</tt>
 * The simplest way to get an <angular/> application up and running is by
 * inserting a script tag in your HTML file that bootstraps the 
 * `http://code.angularjs.org/angular-x.x.x.min.js` code and uses the 
 * special `ng:autobind` attribute, like in this snippet of HTML:
 * 
 * <pre>
    &lt;!doctype html&gt;
    &lt;html xmlns:ng="http://angularjs.org"&gt;
     &lt;head&gt;
      &lt;script type="text/javascript" ng:autobind
              src="http://code.angularjs.org/angular-0.9.3.min.js"&gt;&lt;/script&gt;
     &lt;/head&gt;
     &lt;body&gt;
       Hello {{'world'}}!
     &lt;/body&gt;
    &lt;/html&gt;
 * </pre>
 * 
 * The `ng:autobind` attribute tells <angular/> to compile and manage 
 * the whole HTML document. The compilation occurs in the page's 
 * `onLoad` handler. Note that you don't need to explicitly add an 
 * `onLoad` event; auto bind mode takes care of all the magic for you.
 * 
 * # Manual Bind
 * Using autobind mode is a handy way to start using <angular/>, but 
 * advanced users who want more control over the initialization process 
 * might prefer to use manual bind mode instead.
 * 
 * The best way to get started with manual bind mode is to look at the 
 * magic behind `ng:autobind` by writing out each step of the autobind 
 * process explicitly. Note that the following code is equivalent to 
 * the code in the previous section.
 * 
 * <pre>
    &lt;!doctype html&gt;
    &lt;html xmlns:ng="http://angularjs.org"&gt;
     &lt;head&gt;
      &lt;script type="text/javascript" ng:autobind
              src="http://code.angularjs.org/angular-0.9.3.min.js"&gt;&lt;/script&gt;
      &lt;script type="text/javascript"&gt;
       (function(window, previousOnLoad){
         window.onload = function(){
          try { (previousOnLoad||angular.noop)(); } catch(e) {}
          angular.compile(window.document).$init();
         };
       })(window, window.onload);
      &lt;/script&gt;
     &lt;/head&gt;
     &lt;body&gt;
       Hello {{'World'}}!
     &lt;/body&gt;
    &lt;/html&gt;
 * </pre>
 * 
 * This is the sequence that your code should follow if you're writing 
 * your own manual binding code:
 * 
 * * After the page is loaded, find the root of the HTML template, 
 *   which is typically the root of the document.
 * * Run the HTML compiler, which converts the templates into an 
 *   executable, bi-directionally bound application.
 *   
 * #XML Namespace
 * *IMPORTANT:* When using <angular/> you must declare the ng namespace
 *    using the xmlsn tag. If you don't declare the namespace, 
 *    Internet Explorer does not render widgets properly.
 *    
 * <pre>
 * &lt;html xmlns:ng="http://angularjs.org"&gt;
 * </pre>
 * 
 * # Create your own namespace
 * If you want to define your own widgets, you must create your own 
 * namespace and use that namespace to form the fully qualified 
 * widget name. For example, you could map the alias `my` to your 
 * domain and create a widget called my:widget. To create your own 
 * namespace, simply add another xmlsn tag to your page, create an 
 * alias, and set it to your unique domain:
 * 
 * <pre>
 * &lt;html xmlns:ng="http://angularjs.org" xmlns:my="http://mydomain.com"&gt;
 * </pre>
 * 
 * # Global Object
 * The <angular/> script creates a single global variable `angular`
 * in the global namespace. All APIs are bound to fields of this 
 * global object.
 *
