NelderMead: Implement basic thing from book
ARAPDataTerm: Put surface parameters in a single vector
First pass at a smooth term
ARAP: Last commit on this idea
Another failed attempt at the single iteration correlation
testing: Clean up the pyramidal, iteratively mapping code

It is faster to use the our original NCC code then patch match at the
moment. Maybe don't need patch match. Also, most importantly, I clamp
the blurred disparity so we don't get disparities that are well into
the thousands.
