Tree topic course format

This contributed code module uses the standard topic format and allows the teacher to indent topics to give the course display as a tree.

Features

This course format is one "clone" of the standard "topics" format.
Its main (unique) difference is that, following the indentation in activities performed in edit mode, it displays the course in a tree way.
Specially well integrated with Moodle "standardXXX" themes, see README.txt for some customization possibilities.

Topicstree course format is a Modules and plugins database page for downloads and more information.
