Collision Detection Sources

Well, the last two days I've been researching on the topic of Collision Detection (as planned).

After a short fight against OPCODE (http://www.codercorner.com/Opcode.htm), which stands for OPtimized COllision DEtection, I've been forced to abandon under mere technicalities with its implementation in C++. 

Just couldn't make it compile under gcc and EasyEclipse...anyway, thanks to Pierre Terdiman (http://www.codercorner.com/blog/).

I have switched to PQP (http://gamma.cs.unc.edu/SSV/), which claims to be as fast and memory efficient as OPCODE, and I have already managed to make it work...now let's strip it off!
