     * Creates an observable for an Ajax request with either a request object with

     * ## Example
     * ```ts
     * import { ajax } from 'rxjs/ajax';
   *
     * const source1 = ajax('/products');
     * const source2 = ajax({ url: 'products', method: 'GET' });

     *   A string of the URL to make the Ajax call.
     *   An object with the following properties
     *   - url: URL of the request
     *   - body: The body of the request
     *   - method: Method of the request, such as GET, POST, PUT, PATCH, DELETE
     *   - async: Whether the request is async
     *   - headers: Optional headers
     *   - crossDomain: true if a cross domain request, else false
     *   - createXHR: a function to override if you need to use an alternate
     *   XMLHttpRequest implementation.
     *   - resultSelector: a function to use to alter the output value type of
     *   the Observable. Gets {@link AjaxResponse} as an argument.
     * @return {Observable} An observable sequence containing the XMLHttpRequest.
