	This system uses "update" functions as OnUpdate, and OnEvent handlers.
	This "Initialize" function registers the events to handle.
	The "update" function is set as the OnEvent handler (although they do not parse the event),
	as well as run from the parent's update handler.

	TT: I had to make the spellbar system differ from the norm.
	I needed a seperate OnUpdate and OnEvent handlers. And needed to parse the event.
