• /join <channel> should add the client to the given channel. Clients can only be in one channel at a time, so if the client is already in a channel, this command should remove the client from that channel. When a client is added to a channel, a message should be broadcasted to all existing members of the channel stating that the client has joined. Similarly, if the client left a channel, a message should be broadcasted stating that the client left.

• /create <channel> should create a new channel with the given name, and add the client to the given channel. As with the /join call, the client should be removed from any existing channels.

• /list should send a message back to the client with the names of all current channels, separated by newlines.
