// Class TG4VSDConstruction
// ------------------------
// Abstract class for construction of user sensitive detectors.
// It has one pure virtual method Construct()
// that has to be be implemented by a derived class.
// Constructed sensitive detectors have to inherit from 
// TG4VSensitiveDetector (see TG4VSensitiveDetector.h description);
// all cloned logical volumes (which a single G3 volume correspond to)
// have to share the same sensitive detector instance.
