/**
 * @description Typed global events for events module (`jibo.globalEvents`).
 * Only emits event to LAST subscriber.
 * Also emits when a subscriber is added to a particular event AND
 * when all subscribers have been removed from particular event (no handlers
 * are registered for that event).
 * ```
 * function handler = (data) => {
 *    // data is of type asrResult
 *    // the ASR service has finished listening a cloud result
 *    // and all subscribed listeners will be removed
 * }
 * jibo.globalEvents.touchOn.on(handler);
 * // When finished with event listening
 * jibo.globalEvents.touchOn.removeLastListener();
 * // or
 * jibo.globalEvents.touchOn.removeListener(handler);
 * ```
