   * 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 {ObservableInput} 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` (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.
