Overview

This class started out as a gist somewhere but I can’t seem to find the

original.  At any rate its been modified over time to make it not break
and to update it to make it compatible with Bootstrap2.

If I'm being brutally honest its a bit of a cluster of metaprogramming
and it can be pretty difficult to understand.  BUT it does seem to work
so far.
