also changes the model_invert into a function call instead of using the TF1 class
modified: TrackRecon.C refactor plus removal of older vesions of pcz and track reconstruction from the old analysis. Changed the ranges for dECalib spectra since their max was way too high.
modified: pc_energy_calibration.dat changed the calibration of anode 2-4 to the same as anode1 and 5 to 6 becuase they were causing bifuraction in signal. This might have been happening because the 17F data is poisoning the calibraion. This hypothesis
is pending validation however.
