     * This static operator is useful for creating a simple Observable that only
     * emits the complete notification. It can be used for composing with other
     * Observables, such as in a {@link mergeMap}.
     *
     * @example <caption>Emit the number 7, then complete.</caption>
     * var result = Rx.Observable.empty().startWith(7);
     * result.subscribe(x => console.log(x));
     *
     * @example <caption>Map and flatten only odd numbers to the sequence 'a', 'b', 'c'</caption>
     * var interval = Rx.Observable.interval(1000);
     * var result = interval.mergeMap(x =>
     *   x % 2 === 1 ? Rx.Observable.of('a', 'b', 'c') : Rx.Observable.empty()
     * );
     * result.subscribe(x => console.log(x));
     *
     * // Results in the following to the console:
     * // x is equal to the count on the interval eg(0,1,2,3,...)
     * // x will occur every 1000ms
     * // if x % 2 is equal to 1 print abc
     * // if x % 2 is not equal to 1 nothing will be output
