function [] = GUI_27()
% Demonstrate how to display the current location of the mouse in an axes.
% Run the GUI then move the cursor over the axes.  The current location of 
% the pointer in the axes will be displayed at the top of the plot, in axes
% units. 
% Suggested exercise: Make this function to take an axes handle as an
% input argument, automatically detect the xlim and ylim, and show the
% pointer location in the title.  Even more advanced:  Detect when
% the axes already has a title.  In that case don't overwrite the title, 
% but launch another small GUI which displays the pointer location.
