 @name Tutorial: 11 - REST and Custom Services

 In this step, you will improve the way our app fetches data.

 The last improvement we will make to our app is to define a custom service that represents a {@link
 http://en.wikipedia.org/wiki/Representational_State_Transfer RESTful} client. Using this client we
 can make xhr requests for data in an easier way, without having to deal with the lower-level {@link
 api/angular.service.$xhr $xhr} API, HTTP methods and URLs.

-
 We used the {@link api/angular.service} API to register a custom service. We passed in the name of
 the service - 'Phone' - and a factory function. The factory function is similar to a controller's
 constructor in that both can declare dependencies via function arguments. The Phone service
 declared a dependency on the `$resource` service.
 
-
 The {@link api/angular.service.$resource `$resource`} service makes it easy to create a {@link
 http://en.wikipedia.org/wiki/Representational_State_Transfer RESTful} client with just a few lines
 of code. This client can then be used in our application, instead of the lower-level {@link
 api/angular.service.$xhr $xhr} service.

 ## Controller
 
-
 We simplified our sub-controllers (`PhoneListCtrl` and `PhoneDetailCtrl`) by factoring out the
 lower-level {@link api/angular.service.$xhr $xhr} service, replacing it with a new service called
 `Phone`. Angular's {@link api/angular.service.$resource `$resource`} service is easier to use than
 {@link api/angular.service.$xhr $xhr} for interacting with data sources exposed as RESTful
 resources. It is also easier now to understand what the code in our controllers is doing.

 Notice how in `PhoneListCtrl` we replaced:

       self.phones = response;
     });
 
-
 with:
 
-
     this.phones = Phone_.query();
 
-
 This is a simple statement that we want to query for all phones.
 
-
 An important thing to notice in the code above is that we don't pass any callback functions when
 invoking methods of our Phone service. Although it looks as if the result were returned
 synchronously, that is not the case at all. What is returned synchronously is a "future" — an

 in angular, we can use this future and bind it to our template. Then, when the data arrives, the
 view will automatically update.
 
-
 Sometimes, relying on the future object and data-binding alone is not sufficient to do everything
 we require, so in these cases, we can add a callback to process the server response. The
 `PhoneDetailCtrl` controller illustrates this by setting the `mainImageUrl` in a callback.

 ## Test
 
-
 We have modified our unit tests to verify that our new service is issuing HTTP requests and
 processing them as expected. The tests also check that our controllers are interacting with the
 service correctly.
 
-
 The {@link api/angular.service.$resource $resource} client augments the response object with
 methods for updating and deleting the resource. If we were to use the standard `toEqual` matcher,
 our tests would fail because the test values would not match the responses exactly. To solve the
