// class G4PersistentDigitMan 
//
// A Class responsible for registring DigitsCollection

//
// This class itself is not persistent-capable. 
//
// Member functions:
// =================
//  static G4PersistentDigitMan* GetPersistentDigitMan();
//  static G4PersistentDigitMan* get_PersistentDigitManIfExist();
//   Return ptr to singleton instance of the class.
//
//  G4PersistentDigitMan();
//  ~G4PersistentDigitMan();
//
// Member data:
// ============
// static G4PersistentDigitMan* fPersistentDigitMan
//   Ptr to the unique instance of class
