Starting a Network Server
To start a network server, make a new instance of the class NetworkServer. The NetworkServer class is used for both receiving objects from other breve simulations, and for allowing a web interface to your breve simulation.
Once the NetworkServer instance has been created, it should be told to start listening for connections using the method listen. The listen method expects a port number which must be greater than 1024, but otherwise may be any unused port that both the client and the server breve users have agreed to.
