/*
 *    changed : 10. oct. 03
 *    author  : [email protected]
 *    additional : Martin B. Vestergaard, Adrian Cope
 *    download: http://www.phpclasses.org/browse.html/package/1020.html
 *
 *    description :
 *        a script aimed at cleaning up after mshtml. use it in your wysiwyg html-editor,
 *        to strip messy code resulting from a copy-paste from word.
 *        this script doesnt come anything near htmltidy, but its pure php. if you have
 *        access to install binaries on your server, you might want to try using htmltidy.
 *    note :
 *        you might want to allow fonttags or even style tags. in that case, modify the
 *        function htmlcleaner::cleanup()
 *    usage :
 *        $body = htmlcleaner::cleanup($_POST['htmlCode']);
 *
 *    disclaimer :
 *        this piece of code is freely usable by anyone. if it makes your life better,
 *        remember me in your eveningprayer. if it makes your life worse, try doing it any
 *        better yourself.
 *
 *    todo/bugs :
 *        the script seems to remove textnodes in the root area. (eg. with no enclosing tags)
