- 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.

A grid.boundaryIdentifier identifies a boundary of a grid.
For a Cartesian grid it is simply 's', 'n', 'w', 'e'.
For a multiblock grid it might be something like {1, 's'}.
For some other grid it will be up to the developer to chose
a good way to identify boundaries.
