 *
 * This app is a chat server simulator. Some of the key features:
 * + Create multiple apps for testing the server, default is 2, can add more by editing this file
 * + Create new user, login, logout
 * + Store multiple users and users' messages
 * + Get recent messages when open a chat window to a partner
 * + When logged in, automatically open a chat window when there's an incoming message.
 * + Send message when the partner is offline, store message so that the partner can see it later.
