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