   * Projects each source value to the same Observable which is merged multiple
   * times in a serialized fashion on the output Observable.
   *
   * <span class="informal">It's like {@link concatMap}, but maps each value
   * always to the same inner Observable.</span>
   *
   * <img src="./img/concatMapTo.png" width="100%">
   *
   * 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. Each new `innerObservable`
   * instance emitted on the output Observable is concatenated with the previous
   * `innerObservable` instance.
   *
   * __Warning:__ if source values arrive endlessly and faster than their
   * corresponding inner Observables can complete, it will result in memory issues
   * as inner Observables amass in an unbounded buffer waiting for their turn to
   * be subscribed to.
   *
   * Note: `concatMapTo` is equivalent to `mergeMapTo` with concurrency parameter
   * set to `1`.
   *
   * @example <caption>For each click event, tick every second from 0 to 3, with no concurrency</caption>
   * var clicks = Rx.Observable.fromEvent(document, 'click');
   * var result = clicks.concatMapTo(Rx.Observable.interval(1000).take(4));
   * result.subscribe(x => console.log(x));
   *
   * // Results in the following:
   * // (results are not concurrent)
   * // For every click on the "document" it will emit values 0 to 3 spaced
   * // on a 1000ms interval
   * // one click = 1000ms-> 0 -1000ms-> 1 -1000ms-> 2 -1000ms-> 3
