added latex file for optimization problem statement, which is a bit out of date as Andy's processing takes care of a lot of the elevation issues, two png files linked in the latex file, and a python script called optimzeSFR with some useful utilities for the optimization approach outlined in the problem statement. Maybe useful for eventual report on the SFR work- HWR
