Initialize a SimpleRPC object.

:param host: The host the server will listen on.  It is
             strongly recommended that this always be
             "127.0.0.1", since no cryptography is used.
:param port: The TCP port the server will listen on.
:param authkey: An authentication key.  The server and all
                clients must use the same authentication key.
