+	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
