ChatModel class

Chat Model

이 모델은 채팅방의 데이터 모델이 아니라, 로직을 담고 있는 로직 모델이다. This model is not a data model for the chat room but a logic model containing the logic.

ChatService 에 모든 것을 다 집어 넣으면, 각 채팅 방마다 관리가 어렵고 동시에 두개의 채팅방을 열 수 없다. If all the logic is squeezed inside the ChatService, it is not easy to manage chat room. And it is very difficult to open more than one chat room at the same time. So, ChatModel is created to manage the logic of each chat room. And it is possible to open more than one chat room at the same time.
