+
+/**
+ * @ngdoc object
+ * @name ngResource.$resource
+ * @requires $http
+ *
+ * @description
+ * A factory which creates a resource object that lets you interact with
+ * [RESTful](http://en.wikipedia.org/wiki/Representational_State_Transfer) server-side data sources.
+ *
+ * The returned resource object has action methods which provide high-level behaviors without
+ * the need to interact with the low level {@link ng.$http $http} service.
+ *
+ * # Installation
+ * To use $resource make sure you have included the `angular-resource.js` that comes in Angular 
+ * package. You can also find this file on Google CDN, bower as well as at
+ * {@link http://code.angularjs.org/ code.angularjs.org}.
+ *
+ * Finally load the module in your application:
+ *
+ *        angular.module('app', ['ngResource']);
+ *
+ * and you are ready to get started!
+ *
+ * @param {string} url A parameterized URL template with parameters prefixed by `:` as in
+ *   `/user/:username`. If you are using a URL with a port number (e.g. 
+ *   `http://example.com:8080/api`), you'll need to escape the colon character before the port
+ *   number, like this: `$resource('http://example.com\\:8080/api')`.
+ *
+ * @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 ng.$http} with the specified http method,
+ *   destination and parameters. When the data is returned from the server then the object is an
+ *   instance of the resource class. The actions `save`, `remove` and `delete` are available on it
+ *   as  methods with the `$` 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 = $resource('/user/:userId/card/:cardId',
+      {userId:123, cardId:'@id'}, {
+       charge: {method:'POST', params:{charge:true}}
+      });
+
+     // We can retrieve a collection from the server
+     var cards = CreditCard.query(function() {
+       // GET: /user/123/card
+       // server returns: [ {id:456, number:'1234', name:'Smith'} ];
+
+       var card = cards[0];
+       // each item is an instance of CreditCard
+       expect(card instanceof CreditCard).toEqual(true);
+       card.name = "J. Smith";
+       // non GET methods are mapped onto the instances
+       card.$save();
+       // POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'}
+       // server returns: {id:456, number:'1234', name: 'J. Smith'};
+
+       // our custom method is mapped as well.
+       card.$charge({amount:9.99});
+       // POST: /user/123/card/456?amount=9.99&charge=true {id:456, number:'1234', name:'J. Smith'}
+     });
+
+     // we can create an instance as well
+     var newCard = new CreditCard({number:'0123'});
+     newCard.name = "Mike Smith";
+     newCard.$save();
+     // POST: /user/123/card {number:'0123', name:'Mike Smith'}
+     // server returns: {id:789, number:'01234', name: 'Mike Smith'};
+     expect(newCard.id).toEqual(789);
+ * </pre>
+ *
+ * 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
+       });
+     });
+   </pre>
