0005 //
0006 //   To make plot of layers from a file created using SimHit/Digi/RecHit
0007 //   using the scripts runHFNoseSimHitStudy_cfg.py, runHFNoseDigiStudy_cfg.py,
0008 //   runHFNoseRecHitStudy_cfg.py in Validation/HGCalValidation

0012 //   where
0013 //     fname   std::string   Name of the ROOT file [hfnSimHitD94tt.root]
0014 //     type    int           File type (0:SimHit; 2:Digi; 3:RecHit) [0]
0015 //     todomin int           Range of plots to make    [0]
0016 //     todomax int           (minimum: -1; maximum: 8) [7]
0017 //     tag     std::string   To be added to the name of the canvas [""]
0018 //     text    std::string   To be added to the title of the histogram [""]
0019 //     save    bool          If the canvas is to be saved as jpg file [false]
