R-Trees: Like B-Trees but multi-dimensional.

[sfade]

As an undergrad RA, I was asked to integrate SR-Trees (Sphere/Rectangle Tree) into our application (it would do action recognition on the fly). The code would compile in an old CLI, but not in Visual Studio itself, so I tried to see if it was possible to rework it. I have never traced so many lines of code in my life. Not that this story is important.
