viscosity (Leith) are of the same order that the one from biharmonic viscosity.

The debug parameter I added (OBCS_uvApplyFac) should allow to confirm
that the results no longer depend on normal-component being applied 
to the 2nd grid-point (=beyond the OB).

But one issue with those changes is that very few test-exp are currently
testing momentum wider-stencil scheme with OBCS (in fact, only dome results
are affected). Would be good to test biharmonic diffusivity (un-tested),
constant biharmonic visc (in flux-form) and zStar could be added to the list.
I propose to:
- slightly change exp4 (add Non-Hydrostatic and small viscA4)
- add 2nd exp4 test with zStar (and time-varying OBC ?), but not yet ready.
And was thinking of adding small diffK4T,diffK4S into seaice_obcs to
test biharmonic diffusivity. Other exp using OBCS are not as good test,
either 2-D or starting with weak T,S horiz gradient or don't have the 
4 types of OB (N,S,E,W).
 Dimitris, is it OK with you ? (and in this case would add a comment line 
  next to these 2 param in seaice_obcs/input/data); 
 or should I add a secondary test ? (But is it worth to have 2 tests with so 
 little differences in parameter list ?).
