- Fitting/Calibration removed from FinaliseCalib() function.  From now on SortTrees::Calib() will just build charge histograms, SortHistos will be needed to do the actual calibration.

- Most canvas declarations moved from Calib.C and SortHistos.C to CalibTools.C as they will now only be used with SortHistos.

- Exception to above is cWave canvas which stays with Calib() for debugging of WaveEn calculation

- Temporary histogram calibration from Calib() (used to detect gain drift) now adapted to use new fitting/cvalibration functions.  Last of legacy fitting functions removed from CalibTools.C.

- TempFit bool added to FitSettings structure.  USed to override plots and output when fitting temporary spectra.q
Moved functions in CalibTools into more sensible order.
Added some comments.
