Changes since 1.4: +57 -55 lines
Merging from release1_p12:
o Modifications for using pkg/exf with pkg/seaice
  - improved description of the various forcing configurations
  - added basic radiation bulk formulae to pkg/exf
  - units/sign fix for evap computation in exf_getffields.F
  - updated verification/global_with_exf/results/output.txt
o Added pkg/sbo for computing IERS Special Bureau for the Oceans
  (SBO) core products, including oceanic mass, center-of-mass,
  angular, and bottom pressure (see pkg/sbo/README.sbo).
o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
  to avoid negative values in shallow regions.
  - updated verification/natl_box/results/output.txt
  - updated verification/lab_sea/results/output.txt
o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
o Added useSingleCpuIO option (see PARAMS.h).
o Updated useSingleCpuIO option in mdsio_writefield.F to
  work with multi-field files, e.g., for single-file pickup.
o pkg/seaice:
  - bug fix in growth.F: QNET for no shortwave case
  - added HeffFile for specifying initial sea-ice thickness
  - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
  kpp_transport_t.F, forward_step.F, and the_main_loop.F
o pkg/seaice:
  - adjoint-friendly modifications
  - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
