System.parse() interface

[marco-buttu]

The System.parse() method takes a byte (string of one character, in Python 2) as argument and returns:

• False when the byte is not the header and it is still waiting for the header
• True when it has already got the header and it is composing the message
• the reponse, a non empty string, when there is a response to send back to the client

If the system has nothing to send to the client, as in the case of brodcast requests, System.parse() should return True.

It eventually raises a ValueError in case there is an unexpected error (not considered by the protocol).

ValueError now is raised only in case of unknown protocol command. Still looking for additional events.

The requirement is now implemented in the server. The System.parse() has to use this specification.
