Update of /u/gcmpack/MITgcm/pkg/obcs
In directory forge:/tmp/cvs-serv5609/pkg/obcs

Modified Files:
	obcs_write_pickup.F obcs_read_pickup.F obcs_init_variables.F 
	obcs_calc_stevens.F OBCS_FIELDS.h 
Log Message:
  - fix various problems in the phase speed computations of the Stevens 
    boundary conditions:
    - sign error for western and southern boundaries,
    - time tendencies were underestimated by factor of dTracerLev and some just 
      zero (for multidim advection schemes) -> now estimate time tendencies
      from difference between previous (n) time level and the one before (n-1);
      this requires storing a field per tracer per boundary, also in the pickup 
      files.
    - replace deltaTmom in cflMer/Zon computation with dTracerLev
    - set default phase velocity to cflMer/Zon
  - requires updating verification experiment exp4.stevens
