[Martin Losch]

Update of /u/gcmpack/MITgcm/pkg/seaice
In directory forge:/tmp/cvs-serv24550/pkg/seaice

Modified Files:
	seaice_preconditioner.F 
Log Message:
introduce a restricted additive Schwarz (RAS) method (run LSR into the
overlaps as far as possible, i.e OLx/y-2, but overwrite the solution
in the overlaps)
 - add flexible loop ranges to seaice_preconditioner
 - slightly modify loops in tridiagonal solver lsr-preconditioner
 - by default remove the extra exchange in seaice_preconditioner with a
   replacement of an undocumented CPP flag by
   SEAICE_PRECOND_EXTRA_EXCHANGE

 - change subroutine names seaice_precond_rshu/v to
   seaice_precond_rhsu/v (how did that happen)
