		The 
begin event is called exactly once immediately after the
		artform is displayed on the screen for the first time. This event occurs
		after the 
initialize event
		but before any 
version
		events.
Use this event for any actions which should begin when the user is
		first shown the artform such as starting basic alarm timers.
		| There can only be one begin event. | 
		Example:
		
    ;@ begin()
    ;@   timer(5, 100)                 ; After the art is shown, start timer 5 at 100 milliseconds,
    ;@   notify("Welcome to my doll!") ; and present a welcome message to the user.
