GUI_18()
function [] = GUI_18()
% Demonstrate the use of the buttondownfcn for an axes.  
% Clicking on the axes creates a random line.  Note that clicking on the 
% line does the same thing.  This must be accounted for in the coding 
% below, or clicking on the line would do nothing.  Right click to delete 
% the line.
%
% An exercise would be to alter the code so that right clicking recreates
% the plot in another figure window.  This could be done at least two
% different ways.
