1503 
150415 may 01: L.Urban
1505- new multiple scattering version committed under the class name
1506  G4MultipleScatteringx. It gives better msc angle distribution
1507  than the standard G4MultipleScattering. It uses a distribution
1508  to simulate the geom./true pathlengths (standard : mean values
1509  only) and has a framework implemented in it to perform special
1510  stepping near to a boundary (this algorithm works, but some
1511  further development/tuning needed - this algorithm is disabled
1512  by default). This new version can be used after the change:
1513       G4MultipleScattering  --> G4MultipleScatteringx
1514  in the PhysicsList.
