release1_p16
o fixed gather/scatter inital MPI dialogue in ini_procs.F
o pkg/seaice/lsr.F has been moved to SouthWest B-grid location
  and has been made the default dynamic solver because of its
  fast convergence properties relative to adi.F solver.

1 % need to be in verification/lab_sea/matlab directory
