 CURL - Compute the CURL of a FEM 2-D vector field

        CURL(fem_grid_struct,u,v) computes the curl of a 2-D 
        vector field (u,v) (curl X (u,v)) over the FEM domain 
        specified by fem_grid_struct.  The result is a 2-D 
        scalar field containing the curl, returned to the workspace.

        The computed quantity is:    crl=dv/dx - du/dy

   INPUT : fem_grid_struct (from LOADGRID, see FEM_GRID_STRUCT)
           u,v - u,v vector field

  OUTPUT : crl - curl X (u,v)

    CALL : crl=curl(fem_grid_struct,u,v);

        ALL ARGUMENTS ARE REQUIRED.
