/**
 * 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>
 *
 * <img src="./img/concat.png" width="100%">
 *
 * 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
