+Usage instructions for foldertree.js
+
+foldertree was modified for egw by NDEE 2004
+============================================
+
+detailed instructions follow shortly
+
+Definition of vars passed to function add Node()
+
+ Node(id, pid, name, url, urlClick, urlOut, title, target, icon, iconOpen, open)
+
+where 
+id = increasing number beginning from 0 (-1=Tree-Root)
+pid = id of parent node
+name = name of node
+url = url of node's link
+urlClick = js command for onClick
+urlOut = js command(s) for onMouseOUt
+title = Popup Title
+target = target frame
+icon = icon :)
+iconOpen = special icon when opened
+open = TRUE/FALSE id to make node open on start
+
+vars to follow
+
+urlOver = js command(s) for onMouseOver (dont use currently!)
+urlUp = js command(s) for onMouseUp
