/**
 * Creates a response options object to be optionally provided when instantiating a
 * {@link Response}.
 *
 * This class is based on the `ResponseInit` description in the [Fetch
 * Spec](https://fetch.spec.whatwg.org/#responseinit).
 *
 * All values are null by default. Typical defaults can be found in the
 * {@link BaseResponseOptions} class, which sub-classes `ResponseOptions`.
 *
 * This class may be used in tests to build {@link Response Responses} for
 * mock responses (see {@link MockBackend}).
 *
 * ### Example ([live demo](http://plnkr.co/edit/P9Jkk8e8cz6NVzbcxEsD?p=preview))
 *
 * ```typescript
 * import {ResponseOptions, Response} from '@angular/http';
 *
 * var options = new ResponseOptions({
 *   body: '{"name":"Jeff"}'
 * });
 * var res = new Response(options);
 *
 * console.log('res.json():', res.json()); // Object {name: "Jeff"}

 * The options could also be extended when manually creating a {@link Response}
