// G4ParticleTable
//
// Class description:
//
// G4ParticleTable is the table of pointers to G4ParticleDefinition.
// It is a "singleton" (only one static object).
// Each G4ParticleDefinition pointer is stored with its name as a key
// to itself. So, each G4ParticleDefinition object must have unique
// name.
// Authors: G.Cosmo, 2 December 1995 - Design, based on object model
// H.Kurashige, 27 June 1996 - First implementation
// History:
// - 14 Nov 1997, H.Kurashige - Added messenger
// - 24 Sep 1998, H.Kurashige - Added dictionary for encoding
// - 28 Oct 1999, H.Kurashige - Migration to STL maps
// - 15 Sep 2017, K.L.Genser - Added support for MuonicAtom
