/**
 * Counts the number of emissions on the source and emits that number when the
 * source completes.
 *
 * <span class="informal">Tells how many values were emitted, when the source
 * completes.</span>
 *
 * <img src="./img/count.png" width="100%">
 *
 * `count` transforms an Observable that emits values into an Observable that
 * emits a single value that represents the number of values emitted by the
 * source Observable. If the source Observable terminates with an error, `count`
 * will pass this error notification along without emitting a value first. If
 * the source Observable does not terminate at all, `count` will neither emit
 * a value nor terminate. This operator takes an optional `predicate` function
 * as argument, in which case the output emission will represent the number of
 * source values that matched `true` with the `predicate`.
 *
 * @example <caption>Counts how many seconds have passed before the first click happened</caption>
 * var seconds = Rx.Observable.interval(1000);
 * var clicks = Rx.Observable.fromEvent(document, 'click');
 * var secondsBeforeClick = seconds.takeUntil(clicks);
 * var result = secondsBeforeClick.count();
 * result.subscribe(x => console.log(x));
 *
 * @example <caption>Counts how many odd numbers are there between 1 and 7</caption>
 * var numbers = Rx.Observable.range(1, 7);
 * var result = numbers.count(i => i % 2 === 1);
 * result.subscribe(x => console.log(x));
 *
 * // Results in:
 * // 4
 *
 * @see {@link max}
 * @see {@link min}
 * @see {@link reduce}
 *
 * @param {function(value: T, i: number, source: Observable<T>): boolean} [predicate] A
 * boolean function to select what values are to be counted. It is provided with
 * arguments of:
 * - `value`: the value from the source Observable.
 * - `index`: the (zero-based) "index" of the value from the source Observable.
 * - `source`: the source Observable instance itself.
 * @return {Observable} An Observable of one number that represents the count as
 * described above.
 * @method count
 * @owner Observable
