%DEMNLAB A front-end Graphical User Interface to the demos
%
%	Description
%	This function will start a user interface allowing the user to select
%	different demonstration functions to view. The demos are divided into
%	4 groups, with the demo being executed by selecting the desired
%	option from a pop-up menu.
