  	 * Projects each source value to the same Observable which is flattened multiple

  	 *
  	 * Maps each source value to the given Observable `innerObservable` regardless
  	 * of the source value, and then flattens those resulting Observables into one
  	 * single Observable, which is the output Observable. The output Observables
  	 * emits values only from the most recently emitted instance of
  	 * `innerObservable`.
  	 *
  	 * @example <caption>Rerun an interval Observable on every click event</caption>
  	 * var clicks = Rx.Observable.fromEvent(document, 'click');
  	 * var result = clicks.switchMapTo(Rx.Observable.interval(1000));
  	 * result.subscribe(x => console.log(x));

  	 *
  	 * @param {Observable} innerObservable An Observable to replace each value from
  	 * the source 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 items from the given
  	 * `innerObservable` every time a value is emitted on the source Observable.
  	 * @return {Observable} An Observable that emits items from the given
  	 * `innerObservable` (and optionally transformed through `resultSelector`) every
  	 * time a value is emitted on the source Observable, and taking only the values
  	 * from the most recently projected inner Observable.
  	 * @method switchMapTo
  	 * @owner Observable
