+o exch2: new S/R that only use the cube-tracer (center-position) exchange:
+  for B-grid vector (not yet tested) and C-grid vector (<- only used
+  when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
+o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
+  (#ifdef ALLOW_SALT_PLUME)
+o gather_2d/scatter_2d: removed halo regions
 o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
   scheme and the corresponding test case (under front_relax dir). For now,
   only available with Skew-flux form and not yet tested in realistic set-up.
