0047  * @brief Sensitive detector.
0048  *
0049  * Describes how to store the energy deposited within the detector.
0050  * It derives from two classes: G4VSensitiveDetector and
0051  * G4VFastSimSensitiveDetector. Addition of G4VFastSimSensitiveDetector is
0052  * necessary in order to handle the energy deposits from the fast simulation.
0053  *
0054  * Two ProcessHits() methods are introduced to handle energy deposited from full
0055  * (detailed) simulation, and from fast simulation. The common part is handled
0056  * by RetrieveAdnSetupHit() method.
