Evolution Of Man Pictures

This is the latest evolution of what was once Theo Smith's "TreeVar and HierListBox" project; I've now rewritten it from the ground up, and turned it into a subclass of REALbasic 4.0's ListBox instead of a Canvas. It implements a true hierarchical list, with dragging and dropping of list elements...
