o Added capability for 3D specification of vertical diffusion coefficient.
  This is done by specifying files diffKr3dSfile and diffKr3dTfile that
  contain the 3D vertical diffusivity coefficients.
Modified files: doc/tag-index model/inc/PARAMS.h
  model/src/calc_3d_diffusivity.F, calc_diffusivity.F, ini_mixing.F,
            ini_parms.F, and set_defaults.F
Added missing file verification/tutorial_global_oce_latlon/run/.cvsignore

470 C Note. 20th May 1998
471 C I made a weird discovery! In the model paper we argue
472 C for the form of the preconditioner used here ( see
473 C A Finite-volume, Incompressible Navier-Stokes Model
474 C ...., Marshall et. al ). The algebra gives a simple
475 C 0.5 factor for the averaging of ac and aCw to get a
476 C symmettric pre-conditioner. By using a factor of 0.51
477 C i.e. scaling the off-diagonal terms in the
