C Change defaut to get the same time-stepping for D-grid momentum and
C  C-grid momentum. D-grid velocity used to be stepped forward in time
C  with Adams-Bashforth only on surface pressure term. Tests show that
C  using AB on D-grid coriolis term improves stability (as expected from
C  CD-scheme paper). The following 2 options allow to reproduce old results.
#define CD_CODE_NO_AB_MOMENTUM
#define CD_CODE_NO_AB_CORIOLIS
