In this model, three islands are created:
Wallops, Assateague, and Chincoteague.
Wallops will be the server.

To run this example, launch three processes
on three different machines, one each including the
wallops.params, assateague.params, or chincoteague.params
parameter files.  

If you'd like to run them on the same
machine, you'll need to tweak the parameter files so that
each has a different client port.  The parameter to modify
is:
	exch.client-port = 9030
