Utilities for implementing Modified Preorder Tree Traversal with your Django Models and working with trees of Model instances. MPTT is a technique for storing hierarchical data in a database. The aim is to make retrieval operations very efficient. The trade-off for this efficiency is that performing inserts and moving items around the tree is more involved, as there's some extra work required to keep the tree structure in a good state at all times.
