In directory forge:/tmp/cvs-serv8284/pkg/seaice

Modified Files:
	seaice_calc_residual.F seaice_calc_viscosities.F seaice_evp.F 
	seaice_jfnk.F seaice_lsr.F 
Log Message:
introduce strongly implicit coupling, intended for stabilizing LSR
(following Hutchings et al. 2004) 
  - introduce zetaZ as a global variable (requires adjustments in
    seaice_evp.F and seaice_jfnk.F) and compute analoguously to etaZ
    in seaice_calc_viscosities.F 
  - new flag SEAICEuseStrImpCpl (default off)
  - add new terms zetaZ*du/dy and zetaZ*dv/dx on both sides of the
    momentum equations
