  	 * Projects each source value to an Observable which is merged in the output

  	 *
  	 * Returns an Observable that emits items based on applying a function that you
  	 * supply to each item emitted by the source Observable, where that function
  	 * returns an Observable, and then merging those resulting Observables and
  	 * emitting the results of this merger.
  	 *
  	 * @example <caption>Map and flatten each letter to an Observable ticking every 1 second</caption>
  	 * var letters = Rx.Observable.of('a', 'b', 'c');
  	 * var result = letters.mergeMap(x =>
  	 *   Rx.Observable.interval(1000).map(i => x+i)
  	 * );
  	 * result.subscribe(x => console.log(x));

  	 * @param {function(value: T, ?index: number): Observable} project A function
  	 * that, when applied to an item emitted by the source Observable, returns an
  	 * Observable.
  	 * @param {function(outerValue: T, innerValue: I, outerIndex: number, innerIndex: number): any} [resultSelector]
  	 * A function to produce the value on the output Observable based on the values
  	 * and the indices of the source (outer) emission and the inner Observable
  	 * emission. The arguments passed to this function are:
  	 * - `outerValue`: the value that came from the source
  	 * - `innerValue`: the value that came from the projected Observable
  	 * - `outerIndex`: the "index" of the value that came from the source
  	 * - `innerIndex`: the "index" of the value from the projected Observable
  	 * @param {number} [concurrent=Number.POSITIVE_INFINITY] Maximum number of input
  	 * Observables being subscribed to concurrently.
  	 * @return {Observable} An Observable that emits the result of applying the
  	 * projection function (and the optional `resultSelector`) to each item emitted
  	 * by the source Observable and merging the results of the Observables obtained
  	 * from this transformation.
  	 * @method mergeMap
