Summary

#
  This class is simply a container for several objects
  which then act together as ``radio buttons''.  The objects
  should be subclasses of {Toggle}, but are normally checkboxes.

  The set/unset status of objects in a {CheckBoxGroup} should be set
  with the {set_which_one} method, not by setting the individual items
  directly with their own methods; that would result in confusion.

  NB - the objects in the group must be added to both the {CheckBoxGroup}
  and the dialog box too; a {CheckBoxGroup} is not a {Container}.
