I've run the same dives in the VPM-B Fortran program.  I repeated each dive
with a 1hr surface interval - we should make sure we're not missing
something in repetitive dives in the Subsurface implementation and I don't
know how well this has been tested yet.  I also put in a couple of air
dives.  Yes, I agree a 60 m on air would be irresponsible, this is just
testing a profile.  Output files are attached.

For each of these profiles, the VPM-B plan seems to be ~2m shorter than
Davide's GUE DecoPlanner plan.  I didn't compare against Jocke's MultiDeco
plans because they don't have runtimes and I don't have time right now to
do all the arithmetic.

I'm not sure what ascent and descent rates Davide and Jocke used, but I
used 18 m/min down and 9 m/min up, with last stop at 6 m.  The
configuration parameters are the same as for zero conservatism in
DecoPlanner/MultiDeco/V-Planner/HLPlanner.
