// Class description:
//
// The same material can be used in regions with different cut values,
// and physics processes must prepare several different cross-sections
// for that material.
// The G4ProductionCutsTable has G4MaterialCutsCouple objects, each of
// which consists of a material paired with a cut value.
// G4MaterialCutsCouples objects are numbered with an index which is the
// same as the index of a G4PhysicsVector for the corresponding
// G4MaterialCutsCouple in the G4PhysicsTable.
// The list of G4MaterialCutsCouple objects used in the geometry setup
// is updated before starting the event loop in each run.
 
// Author: H.Kurashige, 17 September 2002 - First implementation
