This module implements the C3 algorithm. I have broken this out 
into it's own module because I found myself copying and pasting 
it way too often for various needs. Most of the uses I have for 
C3 revolve around class building and metamodels, but it could 
also be used for things like dependency resolution as well since 
it tends to do such a nice job of preserving local precedence 
orderings.
