32 //
33 // Class Description:
34 // A G4VParticleChange dedicated to occurence biasing : it
35 // applies weights for non-interaction over a step, and for
36 // interaction at the end of the step (if interaction occurs) on
37 // top of a given particle change, that is the one produced by a
38 // physics process (biased in its final state or not).
