DESCRIPTION: This code intercepts both sides of opensprints/goldsprintsfx
"conversation" to control a visual indication of progress using something
like a phsical clock or a race tree.
This makes it possible to not have a projector that costs more than your rollers.
It also makes it possible to do outdoor or mobile events.

This is free software released under modified BSD (details included in source).
TECHNICAL: This is a basic combination of the client and server software from the
python in a nutshell book. It makes a lot of assumtions and should do a better
job of recovering when the pile of flash or the serial proxy crashes (which
happens).
It creates a server on 5331 (the only port gold sprints checks) and expects
to listen to serproxy on 5330 it talks to the clock on 5332
it should eventually check and start serproxy and the goldsprints programs.
it should also do a better job of recovering from issues created by externals.
It has a lot of number foo (hard coding) in it that should be cleaned up
