Hi exf users,

I am thinking of making a major simplification to the
exf package which should considerably facilitate the
inclusion of new fields and features (such as
constant or cyclic forcing option for each field).
Right now, every field has its own read routine
(exf_set_hflux.F, etc.) which is very cumbersome.

I think that this is historically due to a
misunderstanding of the problems with 'field swapping'
(i.e. only read new forcing field when necessary,
e.g. every 24 hours) in the adjoint.
I think the reasons why there were problems with the
adjoint were not understood at the time the package
was first conceived, and a 'play safe' solution was adopted.

If there are no objections, I'd like to give it a try
and see whether the simplification works.
Please let me know. It's not going to happen immediately,
but maybe in June.

Cheers
-Patrick
