GUI_8()
function [] = GUI_8()
% Demonstrate how to tell which button in a uibuttongroup is selected.  
% Similar to GUI_6 except that a uibuttongroup which enforces exclusivity 
% is used.
%
% Suggested exercise:  Make the editbox change the selected radiobutton.
% Be sure to check that user input is valid.
