OBJ

A task that I've been meaning to do for a long time - read in OBJ files, its a very simple format - a list of vertices and a list of faces.

The nice thing is that its a very common format within CAD software, so can read in mesh data into my apps.

Was stuck on a horribly simple problem for ages - trying to figure out a way to look at things from a calm and rational point of view than just grinding away at problems mindlessly.
