g4mc/physics:
=============
  13.2.01:
     New classes:
       TG4ModularPhysicsList,
       TG4PhysicsConstructorXX,
          XX = EM, Hadron, Optical, SpecialCuts, SpecialControls
	  replaced the previous TG4PhysicsList;
       TG4ParticlesManager, TG4G3PhysicsManager
          - separated from TG4PhysicsManager;	
     
     Renamed/removed classes:
       TG3Cut, TG3CutVector - renamed to TG4G3Cut, TG4G3CutVector
       TG3Flag, TG3FlagVector - renamed to TG4G3Control, TG4G3ControlVector
          - moved to global category (as they are used in TG4Limits)
       TG3ParticleWSP -> TG4G3ParticleWSP
       TG3Units -> TG4G3Units
       TG4SpecialFlags -> TG4SpecialControls
       TG4PhysicsListMessenger -> removed; 
          the commands defined here were moved to TG4Messenger     

  6.6.00:
     TG4PhysicsList: updated according the example N04;
        all particles are instantiated; hadronic processes
	are added;
     TG4PhysicsListMessenger: new class;
        implements commands for selection of the processes
	(setOptical, setHadron, setSpecialCuts/Flags)	 
	     

  28.3.00:
     New subcategory:
     Classes: TG4CutVector, TG4FlagVector, TG4SpecialCuts, TG4SpecialFlags,
              TG4PhysicsList, TG4PhysicsManager, TG4G3Defaults
     Enum types: TG3Cut, TG3Flag, TG3ParticleWSP
