Best practices
Hello. I've been using Ratchet for a while but only now I am realizing doing something wrong. 
In the examples, Chat application's business logic located in the MessageComponentInterface. But if there will be more than just sending messages? Like calculating or game's logic? If store this in the server class - it will become whery big.
Can you please explain me how to organize my code with this library?
Sorry for English, hope you understand me
