// Class description:
//
// This class is a subclass of G4VUserPhysicsList.
// The user should register his/her physics constructors by using:
//   G4VModularPhysicsList::RegsiterPhysics()
// to construt particles and processes.
//
// Only one physics constructor can be registered for each "physics_type".
// Physics constructors with same "physics_type" can be replaced using the
// G4VModularPhysicsList::ReplacePhysics() method.

// The type G4VMPLManager is introduced to encapsulate the methods used by

// the fields encapsulated by the class G4VMPLData. When each thread
// changes the value for these fields, it refers to them using a macro
// definition defined below. For every G4VUserPhysicsList instance,
// there is a corresponding G4VMPLData instance. All G4VMPLData instances
// are organized by the class G4VMPLManager as an array.
// The field "int G4VMPLInstanceID" is added to the class G4VUserPhysicsList.
// The value of this field in each G4VUserPhysicsList instance is the
// subscript of the corresponding G44VUPLData instance.
// In order to use the class G44VUPLManager, we add a static member in the class
// G4VUserPhysicsList as follows: "static G4VMPLManager subInstanceManager".
// Both the master thread and worker threads change the length of the array
// for G44VUPLData instances mutually along with G4VUserPhysicsList
// instances are created.
