List Expand

Trying to make a view that allows someone to go 8+ levels deep into a hierarchy, while still being able to understand where they are in the structure, and being able to quickly navigate back up to the top view, all while not displaying truncated views of the data and also making sure all of the code will be reusable for users who have different permission profiles (each with different visibility) and completely different hierarchy models and groups is no easy task.

I'm close, but now I've just got to test it.
