/**
 * 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"}
 * ```
 *
 * @experimental

     * Creates a copy of the `ResponseOptions` instance, using the optional input as values to
     * override
     * existing values. This method will not change the values of the instance on which it is being
     * called.
     *
     * This may be useful when sharing a base `ResponseOptions` object inside tests,
     * where certain properties may change from test to test.

     * console.log('res.json():', res.json()); // Object {name: "Jeff"}
     * console.log('res.url:', res.url); // https://google.com

/**
 * Subclass of {@link ResponseOptions}, with default values.
 *
 * Default values:
 *  * status: 200
 *  * headers: empty {@link Headers} object
 *
 * This class could be extended and bound to the {@link ResponseOptions} class
 * when configuring an {@link Injector}, in order to override the default options
 * used by {@link Http} to create {@link Response Responses}.
 *
 * ### Example ([live demo](http://plnkr.co/edit/qv8DLT?p=preview))
 *
 * ```typescript
 * import {provide} from '@angular/core';
 * import {bootstrap} from '@angular/platform-browser/browser';
 * import {HTTP_PROVIDERS, Headers, Http, BaseResponseOptions, ResponseOptions} from
 * '@angular/http';
 * import {App} from './myapp';
 *
 * class MyOptions extends BaseResponseOptions {
 *   headers:Headers = new Headers({network: 'github'});
 * }
 *
 * bootstrap(App, [HTTP_PROVIDERS, {provide: ResponseOptions, useClass: MyOptions}]);
 * ```
 *
 * The options could also be extended when manually creating a {@link Response}
 * object.
 *
 * ### Example ([live demo](http://plnkr.co/edit/VngosOWiaExEtbstDoix?p=preview))
 *
 * ```
 * import {BaseResponseOptions, Response} from '@angular/http';
 *
 * var options = new BaseResponseOptions();
