  	 * Applies an accumulator function over the source Observable, and returns the
  	 * accumulated result when the source completes, given an optional seed value.
  	 *
  	 * <span class="informal">Combines together all values emitted on the source,
  	 * using an accumulator function that knows how to join a new source value into
  	 * the accumulation from the past.</span>
  	 *
  	 * <img src="./img/reduce.png" width="100%">
  	 *
  	 * Like
  	 * [Array.prototype.reduce()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/reduce),
  	 * `reduce` applies an `accumulator` function against an accumulation and each
  	 * value of the source Observable (from the past) to reduce it to a single
  	 * value, emitted on the output Observable. Note that `reduce` will only emit
  	 * one value, only when the source Observable completes. It is equivalent to
  	 * applying operator {@link scan} followed by operator {@link last}.
  	 *
  	 * Returns an Observable that applies a specified `accumulator` function to each
  	 * item emitted by the source Observable. If a `seed` value is specified, then
  	 * that value will be used as the initial value for the accumulator. If no seed
  	 * value is specified, the first item of the source is used as the seed.
  	 *
  	 * @example <caption>Count the number of click events that happened in 5 seconds</caption>
  	 * var clicksInFiveSeconds = Rx.Observable.fromEvent(document, 'click')
  	 *   .takeUntil(Rx.Observable.interval(5000));
  	 * var ones = clicksInFiveSeconds.mapTo(1);
  	 * var seed = 0;
  	 * var count = ones.reduce((acc, one) => acc + one, seed);
  	 * count.subscribe(x => console.log(x));
  	 *
  	 * @see {@link count}
  	 * @see {@link expand}
  	 * @see {@link mergeScan}
  	 * @see {@link scan}
  	 *
  	 * @param {function(acc: R, value: T): R} accumulator The accumulator function
  	 * called on each source value.
  	 * @param {R} [seed] The initial accumulation value.
  	 * @return {Observable<R>} An observable of the accumulated values.
  	 * @return {Observable<R>} An Observable that emits a single value that is the
  	 * result of accumulating the values emitted by the source Observable.
  	 * @method reduce
  	 * @owner Observable
