AE: Renamed TemplateCreator to TemplateCreatorModule to show that it is a rootana module and not a utlity class
AE: Rename TemplateCreator to TemplateCreatorModule in the code itself...
AE: Move the ROOT TFile options into TemplateArchive so that we don't try to write to the file if we only want to read from it
AE: Go back to a skeleton TemplateCreatorModule
AE: I think it's best to have getters here to get the fit parameters
AE: Reverse the renaming of HistogramFitFCN since I wasn't aware at how general this is
AE: Also rename TemplateFitFCN to HistogramFitFCN in the code itself
