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