; Description:  A better (?) way of creating a radio box, using subclassing of
;               togglebutton. Note that this version doesn't waste as much
;               memory as radiobox1.lsp because it defines a single
;               entry-callback on the rowcolumn widget instead of forcing each
;               toggle-button to have separate copies of very similar
;               callback-closures. Just load this file to see the example.
