Message:

Implemented optimisation excluding dry cells from flux calculation.
All tests pass and the script run_okushiri_profile.py reports an improvement
in compute_fluxes from 11.25s to 8.58s or 24% faster.
The overall computation was about 40s, so this optimisation improved the
total running time for the problem in question by 7%.

This partially addresses ticket:135
