/**
* 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
