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