     * Create a loop group.
     *
     * Loops can be defined to repeat a set of events constantly for a set number of iterations.
     * Note that events inside a loop should be timed with a zero-base.
     * This means that you should start from 0ms for the inner event's timing and work up from there.
     * The loop event's start time will be added to this value at game runtime.
     *
     * Example:
     * ```
     * // create a loop group
     * const loop = new Loop(1000, 3)
     * loop.Fade(0, 1000, 1, 0.5) // this means sprite will start to fade at 1000, 2000 and 3000 respectively.
     * // add loop group to sprite
     * sprite.loop(loop)
     * ```
     * @param startTime Time in milliseconds/timestamp at which the loop begins.
     * @param count The number of times the loop executes before stopping.
