AVTS-R6 Demonstration Module

["Lesley Thompson" <lesley@dieboldes.com>]

Johnson County has requested a separate Demonstration Module outside the
Testing Module.  In the April election, demonstration units were deployed to
every vote center and we had an enormous amount of trouble keeping them in
the proper mode to act as a demo unit.   Is there a way to have a
"demonstration loop" that does not allow a user to "go back too far" and end
up outside the demonstration area?  Something really simple and idiot-proof.
