// Class Description:
// Compution on saturation effect, which reduce visible energy
// deposition at the step. Default implementation takes into
// account Birks effect. Birks coefficients for some materials
// from G4 database on materials are provided
//
// This class assumed to be G4ThreadLocal, because it is using
// cache value for material
