// Modified:
//
// 18-05-01 V.Ivanchenko Clean up against Linux ANSI compilation
// 23-08-01 new angle and z distribution,energy dependence reduced,
//          Store,Retrieve methods commented out temporarily, L.Urban
// 27-08-01 bugfix in AlongStepDoIt, L.Urban
// 28-08-01 GetContinuousStepLimit and AlongStepDoIt moved to .cc file (mma)
// 11-09-01 G4MultipleScatteringx put as default: G4MultipleScattering (mma)
