templated Traits dealing with Root Histogram filling for standard histograms

Specializatoins of the Traits type must provide the following static functions :

  • Histo create( std::string& name, std::string& title, Axis& axis... ) it should intanciate a new ROOT histogram instance and return it
  • void fillMetaData( Histo& histo, nlohmann::json const& jsonAxis, unsigned int nentries) it should fill metadata in the ROOT histo histogram provides from the list of axis number of entries
  • void fill( Histo& histo, unsigned int nbins, const WeightType& weight ) it should fill the given number of bin with the given values Last point, it should have a static constexpr unsigned int Dimension
