/**
* 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, whith 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', '<br />');
* $more->addParam('parameter for strSomeMoreLocale');
* $more->addParam('more parameter for strSomeMoreLocale');
*
* // and add it also to the orignal 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 <sup>1</sup> strSomeMoreLocale<br />
* // strSomeEvenMoreLocale - some final words
* </code>
