/**
 * Performs http requests using `XMLHttpRequest` as the default backend.
 *
 * `Http` is available as an injectable class, with methods to perform http requests. Calling
 * `request` returns an {@link Observable} which will emit a single {@link Response} when a
 * response is received.
 *
 * ### Example
 *
 * ```typescript
 * import {Http, HTTP_PROVIDERS} from 'angular2/http';
 * @Component({
 *   selector: 'http-app',
 *   viewProviders: [HTTP_PROVIDERS],
 *   templateUrl: 'people.html'
 * })
 * class PeopleComponent {
 *   constructor(http: Http) {
 *     http.get('people.json')
 *       // Call map on the response observable to get the parsed people object
 *       .map(res => res.json())
 *       // Subscribe to the observable to get the parsed people object and attach it to the
 *       // component
 *       .subscribe(people => this.people = people);
 *   }
 * }
 * ```
 *
 *
 * ### Example
 *
 * ```
 * http.get('people.json').observer({next: (value) => this.people = value});
 * ```
 *
 * The default construct used to perform requests, `XMLHttpRequest`, is abstracted as a "Backend" (
 * {@link XHRBackend} in this case), which could be mocked with dependency injection by replacing
 * the {@link XHRBackend} provider, as in the following example:
 *
 * ### Example
 *
 * ```typescript
 * import {MockBackend, BaseRequestOptions, Http} from 'angular2/http';
 * var injector = Injector.resolveAndCreate([
 *   BaseRequestOptions,
 *   MockBackend,
 *   provide(Http, {useFactory:
 *       function(backend, defaultOptions) {
 *         return new Http(backend, defaultOptions);
 *       },
 *       deps: [MockBackend, BaseRequestOptions]})
 * ]);
 * var http = injector.get(Http);
 * http.get('request-from-mock-backend.json').subscribe((res:Response) => doSomething(res));
 * ```
 *
