 110 This demo shows how individual radio buttons can be used to build
 111 more complicated selection mechanisms...
 112 <P>
 113 It uses 2 groups of wx.RadioButtons, where the groups are defined by
 114 instantiation.  When a wx.RadioButton is created with the <I>wx.RB_GROUP</I>
 115 style, all subsequent wx.RadioButtons created without it are implicitly
 116 added to that group by the framework.
