--[[
	Widgets must provide the following functions
		Acquire() - Called when the object is aquired, should set everything to a default hidden state
		Release() - Called when the object is Released, should remove any anchors and hide the Widget
		
	And the following members
		frame - the frame or derivitive object that will be treated as the widget for size and anchoring purposes
		type - the type of the object, same as the name given to :RegisterWidget()
		
	Widgets contain a table called userdata, this is a safe place to store data associated with the wigdet
	It will be cleared automatically when a widget is released
	Placing values directly into a widget object should be avoided
	
	If the Widget can act as a container for other Widgets the following
		content - frame or derivitive that children will be anchored to
		
	The Widget can supply the following Optional Members

	This is a simple grouping container, no selection, no borders
	It will resize automatically to the height of the controls added to it
