-/**
- * Chat client. This client connects to the SGS Skycastle server and processes
chat messages on a channel. Until we have
- * implemented a real chat protocol, the client understands the following
special messages.
- * <p/>
- * From server:
- * <p/>
- * JOIN [sessionId] [nickname] - User with nickname and sessionId has joined
the chat.
- * <p/>
- * QUIT [sessionId] [nickname] - User with nickname and sessionId has left the
chat.
- * <p/>
- * From client:
- * <p/>
- * NICK [newNickname] - User has changed nickname (TODO: this is very sloppy,
with no protection whatsoever against
- * duplicates).
- * <p/>
- * TODO:
- * <p/>
- * The channel-based chat has some issues since the communication is
effectively client-to-client, even though the
- * server acts as the hub for dispatching messages.. It is difficult to
enforce any rules and protect clients from
- * invalid messages. The state of the network may be difficult to keep
consistent across clients (for example, when
- * mapping sessions to nicknames. Each client has to do its own validity
checking and enforce unique nicknames.). See
- * also SkycastleServerListener.
