GUI_19()
function [] = GUI_19()
% Demonstrate how to keep track of the number of times an action is taken 
% and the number of arguments passed.  Here pressing both buttons
% calls the same function (pb2_call), but pushing button one calls pb2_call
% from it's own callback.  Thus the number of arguments received in
% pb2_call is different depending on how it is called.  Pushing either
% button prints to the command window both the total number of button
% pushes and the number of input arguments used in the latest call.
