  \class SOPHYA::HiStatsInitiator
  \ingroup HiStats
  This class performs the initialisation for HiStats module.
  More specifically, it registers PPF handlers for the following classes :
  - Histo
  - HProf
  - HistoErr
  - Histo2D
  - NTuple
  - XNTuple
  - DataTable
  - SwPPFDataTable

  If the system linker/loader handles correctly static object initialisation, there
  is no action required when writing programs. If not, an instance of the class must
  be present before any other operation on the libray classes.
