GUI_5()
function [] = GUI_5()
% Demonstrate how to use a pushbutton to delete bits of string and how to 
% let the user know that their actions are futile.  After the string is 
% deleted completely, the user is informed that there is nothing left to 
% delete if the delete button is pressed again.  A color change accompanies
% this announcement.
%
% Suggested exercise:  Add a counter to S that starts incrementing when the  
% warning is given.  If the user clicks again, close the GUI.
