0041  * Helper class that can be employed in the fast simulation models.
0042  * It allows to deposit energy at given position (G4FastHit), provided it is
0043  * located within the sensitive detector that derives from
0044  * G4VFastSimSensitiveDetector base class.
0045  * An extended example extended/parameterisations/Par03 demonstrates how to use
0046  * G4FastSimHitMaker to create multiple deposits from the fast simulation model.
