Implementing two safety features: 1. Safety caching: the tracks hold the point where safety is computed, and the safety value in that point. When safety is needed in a different point, the method track.GetSafety(new_point) will subtract from the cached value and return the positive remainder or zero otherwise. The GetSafety method can take an accurate limit value, and when the remainder is smaller than this limit the returned safety is zero. It is the user responsibility to call track.SetSafety(pos, safety) whenever the safety is fully recomputed in a new position. 2. Safety calculation usses a new surface model feature to only compute safety accurately when close to boundaries, and only use the aligned bounding box safety when far away. The distance limit is passed as third parameter to AdePTNavigator::ComputeSafety, and must be typically equal to the discrete interaction step.
In this mode the electrons will still do the full physics, but secondaries are supressed. Useful in particular for debugging safety for a single track.

Safety calculation uses a new surface model feature only to compute safety accurately when close to boundaries, and only use the aligned bounding box safety when far away. The distance limit is passed as a third parameter to
AdePTNavigator::ComputeSafety, and must be typically equal to the discrete interaction step.
