// Class TG4G3PhysicsManager
// -------------------------
// This class provides a Geant3 way control
// to Geant4 physics. 
// The G3 cuts and process controls are
// stored in fCutVector and fControlVector vectors.
// These special cuts/controls are activated 
// by registering their physics constructors
// (TG4PhysicsConstructorSpecialCuts, G4PhysicsConstructorSpecialControl)
// to the modular physics list (TG4ModularPhysicsList)
// by physics manager (TG4PhysicsManager).
