 *
 * // get simple success message 'Success'
 * $message = Message::success();
 *
 * // get special notice
 * $message = Message::notice(__('This is a localized notice'));

 *
 * more advanced usage example:
 * <code>
 * // create another message, a hint, with a localized string which expects
 * $hint = Message::notice('Read the %smanual%s');
 * // replace placeholders with the following params
 * $hint->addParam('[doc@cfg_Example]');
 * $hint->addParam('[/doc]');
 * // add this hint as a tooltip
 * $hint = showHint($hint);
 *
 * // add the retrieved tooltip reference to the original message
 * $message->addMessage($hint);
