This is a class of objects that maintains an internal list of gadgets.
Its purpose is to make it easier to layout a group of gadgets.  Any
gadgets that are a member of a groupgclass object are rendered relative to
the groupgclass object's GA_Left and GA_Top attributes.  As new gadgets
are added to the groupgclass object, the groupgclass object's dimensions
grow to enclose the new gadgets.  When the groupgclass object receives an
OM_DISPOSE message, it not only disposes of itself, it also disposes of
all the gadgets in its list.  Groupgclass does not support the gadget
relative flags (GA_RelWidth, GA_RelHeight, GA_RelBottom, and GA_RelRight).
