 * Holds class PMA_Message
 *
 * @author Sebastian Mendel <info@sebastianmendel.de>

/**
 * a single message
 *
 * simple usage examples:
 * <code>
 * // display simple error message 'Error'
 * PMA_Message::error()->display();
 *
 * // get simple success message 'Success'
 * $message = PMA_Message::success();
 *
 * // get special notice 'Some locale notice'
 * $message = PMA_Message::notice('strSomeLocaleNotice');
 *
 * // display raw warning message 'This is a warning!'
 * PMA_Message::rawWarning('This is a warning!')->display();
 * </code>
 *
 * more advanced usage example:
 * <code>
 * // create a localized success message
 * $message = PMA_Message::success('strSomeLocaleMessage');
 *
 * // create another message, a hint, with a localized string which expects
 * // two parameters: $strSomeFootnote = 'Read the %smanual%s'
 * $hint = PMA_Message::notice('strSomeFootnote');
 * // replace %d with the following params
 * $hint->addParam('[a@./Documentation.html#cfg_Example@_blank]');
 * $hint->addParam('[/a]');
 * // add this hint as a footnote
 * $hint = PMA_showHint($hint);
 *
 * // add the retrieved footnote reference to the original message
 * $message->addMessage($hint);
 *
 * // create another message ...
 * $more = PMA_Message::notice('strSomeMoreLocale');
 * $more->addString('strSomeEvenMoreLocale', ' ');
 * $more->addParam('parameter for strSomeMoreLocale');
 * $more->addParam('more parameter for strSomeMoreLocale');
 *
 * // and add it also to the original message
 * $message->addMessage($more);
 * // finally add another raw message
 * $message->addMessage('some final words', ' - ');
 *
 * // display() will now print all messages in the same order as they are added
 * $message->display();
 * // strSomeLocaleMessage 1 strSomeMoreLocale 
 * // strSomeEvenMoreLocale - some final words
