0037  * @brief Detector construction.
0038  *
0039  * Creates a cylindrical detector, with cylinder axis along Z-axis. It is placed
0040  * in the world volume so that its bases are located at z=0 and z=Length.
0041  * Dimensions of the detector (Radius and Length) and material can be set using
0042  * the UI commands.
0043  * Readout geometry of the detector is created, and can be set by UI commands.
0044  * Cells are created along z-axis, azimuthal angle, and radius (cylindrical
0045  * segmentation).
0046  * Sensitive detector Par03SensitiveDetector is attached to the
0047  * cell volume.
0048  * Region for the detector is created as an envelope of the fast simulation.
