[self ObjectiveIRC] is designed to be extended by something like a bot or client.

IRCSocket<--->ParseText

where each is a different class.
IRC should handle things like dcc, files, etc. and should know what servers/channels are joined.

The IRCSocket creates ParseText which is called every time a message comes in. It should also have the ability to handle more than one server.

ParseText simply separates and stores the message from the server in accordance with how incoming messages are formated by the protocol.
