   * Creates an output Observable which sequentially emits all values from every
   * given input Observable after the current Observable.

   * <span class="informal">Concatenates multiple Observables together by
   * sequentially emitting their values, one Observable after the other.</span>

   * Joins this Observable with multiple other Observables by subscribing to them
   * one at a time, starting with the source, and merging their results into the
   * output Observable. Will wait for each Observable to complete before moving
   * on to the next.
   *
   * @example <caption>Concatenate a timer counting from 0 to 3 with a synchronous sequence from 1 to 10</caption>
   * var timer = Rx.Observable.interval(1000).take(4);
   * var sequence = Rx.Observable.range(1, 10);
   * var result = timer.concat(sequence);
   * result.subscribe(x => console.log(x));
   *
   * // results in:
   * // 1000ms-> 0 -1000ms-> 1 -1000ms-> 2 -1000ms-> 3 -immediate-> 1 ... 10
   *
   * @example <caption>Concatenate 3 Observables</caption>
   * var timer1 = Rx.Observable.interval(1000).take(10);
   * var timer2 = Rx.Observable.interval(2000).take(6);
   * var timer3 = Rx.Observable.interval(500).take(10);
   * var result = timer1.concat(timer2, timer3);
   * result.subscribe(x => console.log(x));
   *
   * // results in the following:
   * // (Prints to console sequentially)
   * // -1000ms-> 0 -1000ms-> 1 -1000ms-> ... 9
   * // -2000ms-> 0 -2000ms-> 1 -2000ms-> ... 5
   * // -500ms-> 0 -500ms-> 1 -500ms-> ... 9
