Feature/x3 confix

Ported the confix parser. Seems like it could be pretty useful now that auto can be used.

I also used ```#include "test.hpp"``` like I did with the seek test (seek.cpp). Tongari thought it should be ```#include <test.hpp>``` since the file is one up one directory and is being included via the ```-I``` switch. Let me know what the preferred style is for that.
