 * --------------------------------------------------------------------
 * Application Events
 * --------------------------------------------------------------------
 * Events allow you to tap into the execution of the program without
 * modifying or extending core files. This file provides a central
 * location to define your events, though they can always be added
 * at run-time, also, if needed.
 *
 * You create code that can execute by subscribing to events with
 * the 'on()' method. This accepts any form of callable, including
 * Closures, that will be executed when the event is triggered.
 *
 * Example:
 *      Events::on('create', [$myInstance, 'myMethod']);
