Humphries Submission

Hi guys,

I would like to submit my code. It calculates the ATE, TT, and TUT as requested. I modified the grmEstimation.py file, to correct for the issues I raised on issue tracker. 

The file which is important is grmPostProcessing_mpi.py, which defines and runs the post-processing simulation and performs the needed calculations. The simulation is implemented in parallel using mpi4py. 

I was not sure if you wanted a writeup, but there is an included latex file as well which provides a short write up and summary.

Thanks!,
