   * Converts a higher-order Observable into a first-order Observable by
   * concatenating the inner Observables in order.
   *
   * <span class="informal">Flattens an Observable-of-Observables by putting one
   * inner Observable after the other.</span>
   *
   * <img src="./img/concatAll.png" width="100%">
   *
   * Joins every Observable emitted by the source (a higher-order Observable), in
   * a serial fashion. It subscribes to each inner Observable only after the
   * previous inner Observable has completed, and merges all of their values into
   * the returned observable.
   *
   * __Warning:__ If the source Observable emits Observables quickly and
   * endlessly, and the inner Observables it emits generally complete slower than
   * the source emits, you can run into memory issues as the incoming Observables
   * collect in an unbounded buffer.
   *
   * Note: `concatAll` is equivalent to `mergeAll` 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 higherOrder = clicks.map(ev => Rx.Observable.interval(1000).take(4));
   * var firstOrder = higherOrder.concatAll();
   * firstOrder.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
