[TYPO3-ect] Better trees

[Elmar Hinz]

Hi all,

I have now uploaded the first snapshot of the trees library I am
currenly working on. I primarly need it is a base for the Common
Category Framework (CCF).

The core classes of the library are 80% done. There is a nice BE module
that visualizes the datamodel. Life tests compare to t3lib_treeview and
t3lib_browsetree with your personal pagetree. Although the library works
with different objects the performance is similar and maybe even better
for big trees.

It works on my installation, it has not been tested on others.

Module: Help > Trees

The class model is designed to be a flexible base for many differnt
applications because model and view are strictly separated. Currently
only parent-child relations are supported, but between heterogenious tables.

As usage examples I will prepare an alternative page navigation with
ajax and tree selects for TCE forms.

To test this you can install the example entries from ext_tables.php by
copy and past into phpmyadmin. How can I prepare content for SQL tables,
so that it is filled?

Regards

Elmar
