% DIALOG_DEMO       -     A sample dialog box created using EasyGUI
%
%   S = DIALOG_DEMO   opens a dialog box created using EasyGUI. It waits
%   for the user to complete it and click "Submit", and returns the user
%   input in the structure S. If the user clicks on "Cancel" or closes the
%   window, S is [].
%
%   Note: Currently, the default values for the fields in SAMPLE_DIALOG 
%     are hard-coded, but they can be passed in as parameters to this
%     function (in a input structure, for example).
