- Fix bug when constructing closure for narrow stencils - Update the residual outside of the RK time steps. At least for the inner convergence rate, updating the residual inside does not seem to be required.

function names = getVarname(varargin)
    names = cell(size(varargin));

    for i = 1:numel(varargin)
        names{i} = inputname(i);
    end
