/**
* Admin Message Handler Class
*
* This class provides a reusable wordpress admin messaging facility for setting
* and displaying messages and error messages across admin page requests without
* resorting to passing the messages as query vars.
*
* ## Usage
*
* To use simple instantiate the class then set one or more messages:
*
* `
* $admin_message_handler = new WP_Admin_Message_Handler( __FILE__ );
* $admin_message_handler->add_message( 'Hello World!' );
* `
*
* Then show the messages wherever you need, either with the built-in method
* or by writing your own:
*
* `$admin_message_handler->show_messages();`
*
* @version 1.0.1
