        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
