/**
 * @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 $http} service.
 *
 * Requires the {@link ngResource `ngResource`} module to be installed.
 *
 * @param {string} url A parametrized URL template with parameters prefixed by `:` as in
 *   `/user/:username`. If you are using a URL with a port number (e.g.
 *   `http://example.com:8080/api`), it will be respected.
 *
 *   If you are using a url with a suffix, just add the suffix, like this:
 *   `$resource('http://example.com/resource.json')` or `$resource('http://example.com/:id.json')`
 *   or even `$resource('http://example.com/resource/:resource_id.:format')`
 *   If the parameter before the suffix is empty, :resource_id in this case, then the `/.` will be
 *   collapsed down to a single `.`.  If you need this sequence to appear and not collapse then you
 *   can escape it with `/\.`.
 *
 * @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in
 *   `actions` methods. If any of the parameter value is a function, it will be executed every time
 *   when a param value needs to be obtained for a request (unless the param was overridden).
 *
 *   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 seapph 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 format of {@link
 *   ng.$http#usage_parameters $http.config}:
 *
 *       {action1: {method:?, params:?, isArray:?, headers:?, ...},
 *        action2: {method:?, params:?, isArray:?, headers:?, ...},
 *        ...}
 *
 *   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. If any of
 *     the parameter value is a function, it will be executed every time when a param value needs to
 *     be obtained for a request (unless the param was overridden).
 *   - **`url`** – {string} – action specific `url` override. The url templating is supported just
 *     like for the resource-level urls.
 *   - **`isArray`** – {boolean=} – If true then the returned object for this action is an array,
 *     see `returns` section.
 *   - **`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 $http cache will be used to cache the
 *     GET request, otherwise if a cache instance built with
 *     {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
 *     caching.
 *   - **`timeout`** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise} that
 *     should abort the request when resolved.
 *   - **`withCredentials`** - `{boolean}` - whether to set the `withCredentials` flag on the
 *     XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5
 *     requests with credentials} for more information.
 *   - **`responseType`** - `{string}` - see {@link
 *     https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType requestType}.
 *   - **`interceptor`** - `{Object=}` - The interceptor object has two optional methods -
 *     `response` and `responseError`. Both `response` and `responseError` interceptors get called
 *     with `http response` object. See {@link ng.$http $http interceptors}.
 *
 * @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:

     *    sub-delims    = "!" / "$" / "&" / "'" / "(" / ")"
