Class Description

  Particle data base manager

  This manager can create automatically a list of particles precompiled
  from a Particle data Group table (see Init function)
  or one can read a list of particles from a table via ReadPDGTable.
  To use the second option, do:
     - TDatabasePDG *pdg = new TDatabasePDG();
     - pdg->ReadPDGtable(filename)
  an example of a pdg table can be found in $ROOTSYS/tutorials/pdg.dat

  See TParticlePDG for the description of a static particle.
  See TParticle for the description of a dynamic particle.

 Create PDG database.

 Cleanup the PDG database.

  Particle definition normal constructor. If the particle is set to be
  stable, the decay width parameter does have no meaning and can be set to
  any value. The parameters granularity, LowerCutOff and HighCutOff are
  used for the construction of the mean free path look up tables. The
  granularity will be the number of logwise energy points for which the
  mean free path will be calculated.

  Converts the ISAJET Particle number into the PDG MC number

  Defines particles according to the Particle Data Group

  For questions regarding distribution or content of the MC particle
  codes, contact
  Gary Wagman (GSWagman@LBL.BITNET, LBL::GSWagman, or GSWagman@LBL.GOV).

 static function returning a pointer to a class instance

  Get a pointer to the particle object according to the name given

  Get a pointer to the particle object according to the MC code number

 Print contents of PDG database.

 read list of particles from a file
 if the particle list does not exist, it is created, otherwise
 particles are added to the existing list
 See $ROOTSYS/tutorials/pdg.dat to see the file format
