CenterStage Object Class:  Group
Subclass of the Root class

The Group object allows you to create hierarchical, compound objects
in Geomview.  See the CenterStage documentation, section CREATING
HIERARCHICAL OBJECTS, for more information on how to create and
manipulate groups.

There are no special directives for the Group class, but several of
the standard directives will be inherited by the objects within a
group.

The Axes directive, if not specified by an object in a group, will be
inherited from the group object.

Any sliders, check-boxes, or type-ins that are created by the group
object will be available to all the objects within the group.

Whenever an object within a group is updated, it will first run the
group's Setup script before its own is run.  This way, you can use the
group Setup script to set values for all the objects in the group.
