G4MultipleScatteringx. It gives better msc angle distribution

to simulate the geom./true pathlengths (standard : mean values
only) and has a framework implemented in it to perform special
stepping near to a boundary (this algorithm works, but some
further development/tuning needed - this algorithm is disabled
by default). This new version can be used after the change:
