Had a slight digression today while working on some 3D stuff and took a look at the FBX file format. I had been using OBJ just for basic stuff but decided it was time to look at formats that can support more than what OBJ can do. I took a look at the file format and decided it was easy enough to get done pretty quickly and wrote this. I am thinking about polishing it up into a stb-style library, until then I figured I would share what I have done so far. Feel free to speak up if you have a code suggestion or whatever.
