Category History file
---------------------
This file should be used by G4 developers and category coordinators
to briefly summarize all major modifications introduced in the code
and keep track of all category-tags.
It DOES NOT substitute the CVS log-message one should put at every
committal in the CVS repository !

G4MultipleScatteringx. It gives better msc angle distribution
than the standard G4MultipleScattering. It uses a 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:
G4MultipleScattering --> G4MultipleScatteringx
in the PhysicsList.
