[MITgcm-support] couplimg to EBM

[Patrick Heimbach]

Hi Chris, Hezi,

I assume(?), Hezi knows the pkg/ebm model since 
Yossi Ashkenazy has been using (and improving?) that one.
So it seems they'd like to try a different one.

The question seems whether you'd like to go through
the coupler (which means you'd have to run on several processors),
or whether you'd just interface through the fluxes Qnet, EmPmR,
i.e. follow the way ebm/ interfaces with the model.
If the latter, not sure whether there's a straightforward way 
of doing asynchronous timestepping (although shouldn't be too 
hard to do via different_multiple).

-Patrick
