[Mitgcm-support] KPP version

[mitgcm-support at dev.mitgcm.org]

Dimitri,

I made the following changes since I took your code:

 o The terms that were #ifdef in calc_diffusivity() are now
    done by routines *_calc_diff() which can either add their
     contribution or overwrite the existing values.
 o kpp_calc_diff() currently does what I think you were talking
    about in our emails involving Detlef and background diffusivity.
    I'm not clear on what it is you wanted so please take a look
    and see if it makes sense.
 o Obviously I didn't incorporate kpp_do_diags or KPP_DIAGS.h
    from your version.

I think everything else is in there.

Now that kpp and gmredi are packaged and in separate locations
(you have model/kpp, we have pkg/kpp) we should assign a tag
to each version of each package. Would you be happy with
kpp_1.0 and gmredi_1.0 for what we have now?
