 103 This demo shows how individual radio buttons can be used to build
 104 more complicated selection mechanisms...
 105 <P>
 106 It uses 2 groups of wxRadioButtons, where the groups are defined by
 107 instantiation.  When a wxRadioButton is created with the <I>wxRB_GROUP</I>
 108 style, all subsequent wxRadioButtons created without it are implicitly
 109 added to that group by the framework.
