Copy StateTL_calibration_inputdata.csv and StateTL_calibration_cont…rol.txt to working directory for repeatability.
Added additional statistical metrics: Mean Absolute Error (MAE, Root Mean Squared Error (RMSE) and Root Mean Percent Squared Error (RMSPE) both globally and by reach. It should be straightforward to add more statistical measures.
The RMSE and RMSPE still need a qaqc check. RMSPE particularly since I had to deal with division by zero by forcing the error in these cases to 0. Maybe RMSPE is not providing the information we want. @LyonsR please pull the updates for qaqc and OAT sensitivity analysis.
