Spatial Sorting with kd-trees - Part 2

Here's the paper itself. The teacher required that I use the ACM format, but I cut corners where possible (e.g. he only said we needed to have those four sections) :P I should note that the sections themselves are from specifications given by the teacher. I think if it were an ACM paper, or even if I was coming up with the structure myself, it would have been organized significantly differently.
