coefficient by the local mesh size. Previously, the absorbing layer coefficient was scaled by dx/dx_fine. For large values of dx/dx_fine instabilities have been ancountered associated with this scaling of the absorbing layer coefficient. Units have been added to the configuration variable config_xnutr (1/s) in the Registry - it is used in calculating the absorbing layer coefficient. Units have also been added to config_visc4_2dsmag (m/s) in the Registry - it is used in the calculation of the hyperviscosity.

This commit removes the scaling of the gravity-wave absorbing layer coefficient by the local mesh size. Previously, the absorbing layer coefficient was scaled by dx/dx_fine.
