 * decide to create a new room or not.

 * @param password the password to use.
 * @param history the amount of discussion history to receive while joining a room.
 * @param timeout the amount of time to wait for a reply from the MUC service(in milleseconds).
 * @throws XMPPException if an error occurs joining the room. In particular, a
 *      401 error can occur if no password was provided and one is required; or a
