SardanaChat, communication between BL scientist and remote user I

SardanaChat allows the beamline scientist and the remote user to exchange messages. The application is launched by:

 
$ SardanaChat3.py 
  by BL scientist
$ SardanaChat3.py 
  remote user1
$ SardanaChat3.py 
  remote user2

These statements apply:

• The first to start the application is the master

• The master prepares N ports for connections. A re-connecting client eats-up another port, in other words: no real garbage collection so far.

• If the master terminates, all clients terminate as well.

• Each participant may set an alias. This is a string identifying the sender. If no alias is set, the connection number is used, 0 is the master.
