Major work on the format and handling of output files.
   - Calib() function now saves the fits it performs with the histograms making it easier to go back and inspect and strange results.
   - CalibOffline() now opens an output file (CalibOffOut.root) and saves histos and fits for any spectra it handles.
   - all output files including root files with histos and text files are now saved at a location specified by "Config.OutPath", default is "./"
   - output path can be changed with -o at the command line.
Also some minor changes to comments
