 * RoomConfiguration is a packet that helps to set the configuration of MUC rooms. RoomConfiguration

 * Map<String,Collection<String>> fields = new HashMap<String,Collection<String>>();
 * // Make a non-public room
 * List<String> values = new ArrayList<String>();
 * values.add("0");
 * fields.put("muc#roomconfig_publicroom", values);
 *
 * // Create a RoomConfiguration with the fields and values
 * RoomConfiguration conf = new RoomConfiguration(fields);
 * conf.setTo("room@conference.jabber.org");
 * conf.setFrom("john@jabber.org/notebook");
 *
 * component.sendPacket(conf);
