[CF-metadata] new named fields for ocean

Dear Stephen,

Thank you for this.  It's always encouraging to see other ocean
modellers getting involved in CF! (I've been struggling to make NEMO
output CF-compliant recently.)

It seems that quite a lot of your proposed names are duplicates of
existing ones, eg
rainfall_flux, surface_downward_x_stress, heat_flux_correction,
surface_downward_latent_heat_flux, ocean_vertical_momentum_diffusivity,

Have you run your names through the latest CF standard_name table at
name-table.html ?
It would show up such coincidences. And many of the entries in this
table have descriptions attached to them, which may indicate whether:
(a) the existing name means what you want it to mean, when they
coincide; or 
(b) your field already exists under a different standard_name.

A few points:

(1) There are no standard_names including "laplacian" yet - it would
seem to be the default (coeffs in m2/s). 

(2) There are lots of "ocean_vertical_..." diffusivities (see table);
perhaps you need to to preface yours as "ocean_lateral_..."  (I don't
know; I'm no expert.)

(3) Are you proposing that cell_thickness be introduced as a new
cell_measure attribute (see Sec 7.2 of CF manual)?  That way all fields
"tied to" the cell_thickness could access it through post-processing
