  	 * Projects each source value to an Observable which is merged in the output
  	 * Observable, emitting values only from the most recently projected Observable.
  	 *
  	 * <span class="informal">Maps each value to an Observable, then flattens all of
  	 * these inner Observables using {@link switch}.</span>
  	 *
  	 * <img src="./img/switchMap.png" width="100%">
  	 *
  	 * 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 (so-called "inner") Observable. Each time it observes one of these
  	 * inner Observables, the output Observable begins emitting the items emitted by
  	 * that inner Observable. When a new inner Observable is emitted, `switchMap`
  	 * stops emitting items from the earlier-emitted inner Observable and begins
  	 * emitting items from the new one. It continues to behave like this for
  	 * subsequent inner Observables.
  	 *
  	 * @example <caption>Rerun an interval Observable on every click event</caption>
  	 * var clicks = Rx.Observable.fromEvent(document, 'click');
  	 * var result = clicks.switchMap((ev) => Rx.Observable.interval(1000));
  	 * result.subscribe(x => console.log(x));
  	 *

  	 * @see {@link switch}
  	 * @see {@link switchMapTo}
  	 *
  	 * @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
  	 * @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 taking only the values from the most recently
  	 * projected inner Observable.
  	 * @method switchMap
  	 * @owner Observable
