27    C     | "Correction Step"
28    C     | =================
29    C     | Here we update the horizontal velocities with the surface
30    C     | pressure such that the resulting flow is either consistent
31    C     | with the free-surface evolution or the rigid-lid:

47    C     |
48    C     | "Time-stepping" or "Prediction"
49    C     | ================================
50    C     | The models variables are stepped forward with the appropriate
51    C     | time-stepping scheme (currently we use Adams-Bashforth II)
52    C     | - For momentum, the result is always *only* a "prediction"
53    C     | in that the flow may be divergent and will be "corrected"
54    C     | later with a surface pressure gradient.
55    C     | - Normally for tracers the result is the new field at time
56    C     | level [n+1} *BUT* in the case of implicit diffusion the result
57    C     | is also *only* a prediction.
58    C     | - We denote "predictors" with an asterisk (*).
59    C     |   U* = U[n] + dt x ( 3/2 Gu[n] - 1/2 Gu[n-1] )
60    C     |   V* = V[n] + dt x ( 3/2 Gv[n] - 1/2 Gv[n-1] )
61    C     |   theta[n+1] = theta[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] )
62    C     |   salt[n+1] = salt[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] )
63    C     | With implicit diffusion:
64    C     |   theta* = theta[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] )
65    C     |   salt* = salt[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] )
66    C     |   (1 + dt * K * d_zz) theta[n] = theta*
