--[[
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
