 * Implements the "throttle first" mechanism for click listeners, to prevent double taps.

 * How it works:
 * - Define a sampling window time (default: 500ms)
 * - when you click at time T0, the first click gets dispatched and the subsequent ones happening
 *   between T0 and T0 + WindowTime gets ignored
