/**
* 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
