Offline calibration will now check filename for type of input:
   - Name matches that set for Config.CalOut - assumes file was generated by this code and searches for histograms and sets parameters accordingly.
   - Name matches "his*" - assumes file comes from TIGRESS DAQ analyser.  Searches for TFolder called "histos" and looks for spectra in there.  Changes histonames.  Outputs both name types.  integration and dispersion set to zero as this is removed in analyser before spectra are incremented.
