   3 ButtonBar widget
   4 Rick Lawson
   5 r_b_lawson at yahoo dot com
   6 Easy widget to mimic the ButtonBar which is showing up a lot in Windows
   7 Inspired by Iuri Wickert's notebook.py widget (esp. the Radiobutton tricks)
   8 
   9 config options
  10 --------------
  11 BusyBar is derived from frame so all frame options are fine
  12 Here are the options specific to this widget
  13 labels = sequence of button labels
  14 images = sequence of PhotoImage objects
  15 commands = sequence of commands to be executed when particular button is selected
