 * Application Events
12
 * --------------------------------------------------------------------
13
 * Events allow you to tap into the execution of the program without
14
 * modifying or extending core files. This file provides a central
15
 * location to define your events, though they can always be added
16
 * at run-time, also, if needed.
17
 *
18
 * You create code that can execute by subscribing to events with
19
 * the 'on()' method. This accepts any form of callable, including
20
 * Closures, that will be executed when the event is triggered.
21
 *
22
 * Example:
23
 *      Events::on('create', [$myInstance, 'myMethod']);
