Generalize previous shelfwater diagnostics.
Generalize previous shelfwater diagnostics.

1. Calculate them for slope and eddy waters.
2. Calculate vertical structure of fluxes east and west of eddy.
3. Calculate fluxes binned by cross-isobath source location.
4. Added initialization to hopefully speed things up.
