Yep.

This patch was more in the area of RFC, sorry for not putting that in
subject.

I started out with single dive calculations, and currently trying
to figure out where to store the CNS information, so we can propagate it
in-between the dives.
My current guess is to shoe-horn it into init_decompression somehow, or
trying to propagate it in fill_dive_list.
Does those sound like a acceptable ideas?
