Challenge: Make a data type for holding one of 8 directions allowing increment and overflow

[Richard (Rikki) Andrew Cattermole]

Bit fields are currently going through the DIP process, although because 
of ImportC having it, its just a matter of turning them on and adding 
the parser stuff.

However there is a major drawback to it and is why you'll still need to 
use a struct and that is you can't take a pointer to it.
