   * Flattens an Observable-of-Observables by applying {@link combineLatest} when the Observable-of-Observables completes.
   *
   * ![](combineAll.png)
   *
   * `combineAll` takes an Observable of Observables, and collects all Observables from it. Once the outer Observable completes,
   * it subscribes to all collected Observables and combines their values using the {@link combineLatest}</a> strategy, such that:
   *
   * * Every time an inner Observable emits, the output Observable emits
   * * When the returned observable emits, it emits all of the latest values by:
   *    * If a `project` function is provided, it is called with each recent value from each inner Observable in whatever order they
   *      arrived, and the result of the `project` function is what is emitted by the output Observable.
   *    * If there is no `project` function, an array of all the most recent values is emitted by the output Observable.
   *

   * ## Examples
   *
   * ### Map two click events to a finite interval Observable, then apply `combineAll`
   *
   * ```ts
   * import { fromEvent, interval } from 'rxjs';
   * import { map, combineAll, take } from 'rxjs/operators';
   *
   * const clicks = fromEvent(document, 'click');
   * const higherOrder = clicks.pipe(
   *   map(ev =>
   *      interval(Math.random() * 2000).pipe(take(3))
   *   ),
   *   take(2)
   * );
   * const result = higherOrder.pipe(
   *   combineAll()
   * );
   *
   * result.subscribe(x => console.log(x));
   * ```
   *
   * @see {@link combineLatest}
   * @see {@link mergeAll}
   *
   * @param {function(...values: Array<any>)} An optional function to map the most recent values from each inner Observable into a new result.
   * Takes each of the most recent values from each collected inner Observable as arguments, in order.
   * @return {Observable<T>}
   * @name combineAll
