I was under the impression that get_function_gradients calculates the gradient
based on the \sum_j U_j that are on the face.
No, it takes the entire sum and evaluates it at a point that happens to be on
the face. But other than where the point happens to be located, the sum is
exactly the same as if it were a point in the interior of the cell.
