MPTtree, Hieararchical trees in a database table

[eluser]m4rw3r[/eluser]
Current Version: 0.1.6-fix2


MPTtree is a model to handle trees in a Nested Sets structure in a database table.

Features:
xpath and paths to nodes
ORM (currently without the relationship part), will be somewhat integrated with IgnitedRecord in the future
Iterators (Only for PHP 5)
Multiple instances with help of custom loader (optional)
A simple admin interface, using Ext JS for drag n drop (a separate zip file, in wiki)
Insertion, Moving, Deletion and Validation methods


Now I have released version 0.1.6 which has got a few bug fixes, a new tree2array method and get_descendants have been modified so they additionally can return a depth column (only non ORM).

0.1.6-fix contains some additional bug fixes.

MPTtree have currently only been tested with MySQL 5, and the queries are currently only written for MySQL (if someone wants to help me to port the SQL to other databases, or is it needed?).

Included in the zip file is a (good?) manual which describes most of the methods (if not all you need to know).
