/**
 * Creates `Request` instances from provided values.
 *
 * The Request's interface is inspired by the Request constructor defined in the [Fetch
 * Spec](https://fetch.spec.whatwg.org/#request-class),
 * but is considered a static value whose body can be accessed many times. There are other
 * differences in the implementation, but this is the most significant.
 *
 * `Request` instances are typically created by higher-level classes, like {@link Http} and
 * {@link Jsonp}, but it may occasionally be useful to explicitly create `Request` instances.
 * One such example is when creating services that wrap higher-level services, like {@link Http},
 * where it may be useful to generate a `Request` with arbitrary headers and search params.
 *
 * ```typescript
 * import {Injectable, Injector} from 'angular2/angular2';
 * import {HTTP_PROVIDERS, Http, Request, RequestMethods} from 'angular2/http';
 *
 * @Injectable()
 * class AutoAuthenticator {
 *   constructor(public http:Http) {}
 *   request(url:string) {
 *     return this.http.request(new Request({
 *       method: RequestMethods.Get,
 *       url: url,
 *       search: 'password=123'
 *     }));
 *   }
 * }
 *
 * var injector = Injector.resolveAndCreate([HTTP_PROVIDERS, AutoAuthenticator]);
 * var authenticator = injector.get(AutoAuthenticator);
 * authenticator.request('people.json').subscribe(res => {
 *   //URL should have included '?password=123'
 *   console.log('people', res.json());
 * });
 * ```
