     * This static operator is useful for creating a simple Observable that emits
     * neither values nor errors nor the completion notification. It can be used
     * for testing purposes or for composing with other Observables. Please note
     * that by never emitting a complete notification, this Observable keeps the
     * subscription from being disposed automatically. Subscriptions need to be
     * manually disposed.
     *
     * @example <caption>Emit the number 7, then never emit anything else (not even complete).</caption>
     * function info() {
     *   console.log('Will not be called');
     * }
     * var result = Rx.Observable.never().startWith(7);
     * result.subscribe(x => console.log(x), info, info);
