+* \brief Definition of the G4ChannelingFastSimInterpolation class
+* The class includes spline interpolation coefficients for the important functions
+* needed in Channeling FastSimulation model, i.e. electric fields, nuclear and
+* electron densities and minimum energy of ionization. All the functions have
+* transverse coordinates as arguments (x for crystal planes, x and y for crystal axes).
+* All the functions are calculated in the co-rotating reference system (along crystal
+* planes/axes).
