     * var numbers = Rx.Observable.range(1, 10);
     * numbers.subscribe(x => console.log(x));
     *
     * @see {@link timer}
     * @see {@link interval}
     *
     * @param {number} [start=0] The value of the first integer in the sequence.
     * @param {number} [count=0] The number of sequential integers to generate.
     * @param {Scheduler} [scheduler] A {@link IScheduler} to use for scheduling
     * the emissions of the notifications.
     * @return {Observable} An Observable of numbers that emits a finite range of
     * sequential integers.
