 // G4BOptnForceFreeFlight
 //
 // Class Description:
-//    A G4VBiasingOperation physics-based biasing operation.
-//    If forces the physics process to not act on the track.
-//    In this implementation (meant for the ForceCollision
-//    operator) the free flight is done under zero weight for
-//    the track, and the action is meant to accumulate the weight
-//    change for making this uninteracting flight,
-//    cumulatedWeightChange.
-//    When the track reaches the current volume boundary, its
-//    weight is restored with value :
-//            initialWeight * cumulatedWeightChange
