+checkpoint43
+o added two new advection tests
+o added global 4x4 degree ocean test
+o added test of H&S94 with free surface on cube
+o some final mods for gradient check, adjoint,...
+
+checkpoint42
+  Fixed AD-related problems:
+o Store directives up-to-date with re-arranged Adams-Bashforth
+  (mainly thermodynamics.F)
+o New store directives for multi-dim. advection schemes
+  * new CPP flag ALLOW_MULTI_DIM_ADVECTION
+  * new common block and key passkey
+  (mainly gad_advection.F)
+o Modified store directives for split of dynamics/thermodynamics
+  for the case ALLOW_KPP
+o Cleaned argument list for timestep_tracer.F

+checkpoint40
+o moved calc_gs, calc_gt and calc_tr1 back to model/src
+o added FLT (floats) package from Arne along with demo. experiment
+o re-arranged Adams-Bashforth scheme for tracers to allow easier
+  implementation of forward-in-time forcing terms
+o more mods for non-linear free-surface including new variable
+o modified multi-dim method to work on cube
