/** \disctab.php
* \wikipedialike discussion tab for pmwiki
*
* see also http://www.pmwiki.org/wiki/Cookbook/DiscussionTab
* Provide a tabbed skin with the possibility to have an "discussion"-tab 
* and an "article"-tab as a kind of backlink to the Main Article.
*This one works for me but it's not well coded I think. I am not a programmer
* and I haven't the time to improve my small php knowledge to get it work better.
* Maybe someone find it usefull. If there is some help to improve this ifeel free to publish it.
