[Doxygen-develop] Treeview v.4

[<mat...@vo...>]

Hi,

I have noticed that an earlier version of tree view is used by Doxygen. That
version needs very long time to display larger tree.

I have managed to convert the tree.js to the format that can be used by TreeView
v.4 using sed and the performance is much better.

I suggest that next versions of Doxygen use newer version of TreeView if it is
not prohibited due to licensing.

P.S.: I have attached new tree.html and a conversion script if you want to use
it with any version of Doxygen. The TreeView sources can be found on the site
mentioned above.
