What happened to 'experimental'?


Hi, I was wanting to play with the tree widget referenced on you docs
page (http://docs.jquery.com/Ui), but it points to an 'experimental'
folder in svn which I am not seeing. Also, all links to it that I
have seen seem to be m.i.a. as well. For example:
http://dev.jquery.com/view/trunk/ui/experimental/tests/tree.html. I
am trying to get jquery into our project, but need a good tree widget
(even if it is in beta form). I ave seen the treeview plguin, which
might do (have to check how well it works with async, saw there is
some support at least), but I would rather use an early 'official' one
if I can. thanks
