I think this comparison is unfair ;-) the collider is complicated
conceptually, although the basic unoptimized variant, without periodic
boundary etc, was quite clean code (then it was velocity bins, periodicity
etc that made the code complex).

For geometry, those things are conceptually quite clean and can be coded
cleanly.

No time, later. Bye,v
