// The type G4VUPLManager is introduced to encapsulate the methods used by
// both the master thread and worker threads to allocate memory space for
// the fields encapsulated by the class G4VUPLData. 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 G4VUPLData instance. All G4VUPLData instances
// are organized by the class G4VUPLManager as an array.
// The field "int g4vuplInstanceID" 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 G4VUPLManager subInstanceManager".
// Both the master thread and worker threads change the length of the array
// for G44VUPLData instances mutually along with G4VUserPhysicsList
// instances are created. For each worker thread, it dynamically creates ions.
// Consider any thread A, if there is any other thread which creates an ion.
// This ion is shared by the thread A. So the thread A leaves an empty space
// in the array of G4PDefData instances for the ion.
//
// Important Note: you may wonder why we are introducing this mechanism
//                 since there is only one PL for each application.
//                 This is true, in the sense that only one PL is allowed
//                 to be associated to a G4RunManager, however user can instantiate
//                 as many PLs are needed and at run-time select one of the PLs to be used
//                 we thus need this mechanism to guarantee that the system works without
//                 problems in case of this (unusual) case. This may be reviewed in the future
