+* \brief Definition of the G4ChannelingFastSimCrystalData class
+* The class inherits G4VChannelingFastSimCrystalData containing the data and properties
+* related to the crystal lattice.
+* The functions related to the crystal geometry (transformation of coordinates and angles
+* from the reference system of the bounding box of the local volume to
+* the crystal lattice co-rotating reference system and vice versa) and
+* initialization function SetMaterialProperties are compiled in this class.
