+ * 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']);
