document this: pkg/seaice: 
 - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
  1. introduce fields for time step (N-1)
  2. do not use levels 2 and 3 anymore (but keep them)
  3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This 
     includes changes to pkg/thsice/thsice_get_velocity.F, 
     model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
     pkg/obcs/obcs_apply_uvice.F.
 - completely remove code for leap-frog time stepping for second order
