o Include a new diagnostic variable phiHydLow for the ocean model
  - in z-coordinates, it is the bottom pressure anomaly
  - in p-coordinates, it is the sea surface elevation
  - in both cases, these variable have global drift, reflecting the mass
    drift in z-coordinates and the volume drift in p-coordinates
  - included time averaging for phiHydLow, be aware of the drift!
o depth-dependent computation of Bo_surf for pressure coordinates
  in the ocean (buoyancyRelation='OCEANICP')
  - requires a new routine (FIND_RHO_SCALAR) to compute density with only
    Theta, Salinity, and Pressure in the parameter list. This routine is
    presently contained in find_rho.F. This routine does not give the
    correct density for 'POLY3', which would be a z-dependent reference
    density.
o cleaned up find_rho
  - removed obsolete 'eqn' from the parameter list.
o added two new verification experiments: gop and goz
  (4x4 degree global ocean, 15 layers in pressure and height coordinates)

19 jmc 1.12 C etaN - free-surface r-anomaly (r unit) at current time level
20 cnh 1.1 C uVel - zonal velocity (m/s, i=1 held at western face)
21     C vVel - meridional velocity (m/s, j=1 held at southern face)
22     C theta - potential temperature (oC, held at pressure/tracer point)
23     C salt - salinity (ppt, held at pressure/tracer point)
24 cnh 1.4 C gX, gXNM1 - Time tendencies at current and prvious time levels.
25     C uVelD - D grid zonal velocity
26     C vVelD - D grid meridional velocity
27 jmc 1.16 C etaH - surface r-anomaly, advanced in time consistently
28     C with 2.D flow divergence (Exact-Conservation):
29     C etaH^n+1 = etaH^n - delta_t*Div.(H^n U^n)
30     C note: a) used with "exactConserv" but strictly necessary for NonLinFreeSurf
31     C b) same as etaN but not necessarely at the same time, e.g.:
32     C implicDiv2DFlow=0 => etaH=etaN ; =1 => etaH=etaNm1 ;
