// GEANT 4 class header file
//
// Class Description:
//   This function implements a simplified "garbage collection" mechanism
//   for G4-MT model. Objects are registered when created on the heap and they 
//   will be deleted at the end of
//   the program (like they would be if marked as "static").
// 
// Limitation:
//   The registered object, should not
//   contain any G4ThreadLocal data member. Note that in general,
//   if object is to be thread-private it is unnecessary to mark
//   any data-member as G4ThreadLocal.
//
// Performance issues:
//   This function uses G4ThreadLocalSingleton that on its own uses
//   locks and mutexes. Thus its use should be limited to only when 
//   really necessary.
//
// Example:
//   class G4SharedByThreads {
//     void calledByThreads() {
//          G4Something* anObject = new G4Something;
//          G4AutoDelete::Register( anObject );
//     }
//   };
//
// History:
//  28 October 2013: A. Dotti - First implementation
