Full Momentum Coupling between WW3-MPASO-EAM

[erinethomas]

NEW WAVE COUPLING FEATURE
Full momentum coupling between WW3, MPAS-Ocean, and EAM is being implemented.
This discussion is for the purpose of getting a preliminary code review and feedback before an official PR is opened into E3SM.

A table summarizing all testing being performed is at the bottom of the page here:

Suggestions welcome for additional testing that is needed to open a PR into E3SM.

The use of WW3 is 'stealth' in that WW3 is NOT a standard feature of E3SM. However, the implementation of wave-ocean-atm coupling in this PR defines the default coupling based upon the COMPSET used.
For example, a fully coupled base with active waves (B compset + WW3) will assume full, two-way coupling between WW3-EAM-MPASO and MPAS-SI. (note: limited wave-ice coupling for now, full wave-ice coupling coming soon). On the other hand, if a data atmosphere used, like in a G Case +WW3, EAM-WW3 coupling will default to "one-way" (data winds passed to WW3) while full two way coupling between WW3 and MPAS-O/MPAS-SI.
