Use a plain pointer in the FEValuesView classes. This may not be as safe, but then the view objects usually exist only for a very short time anyway, and using plain pointers makes the current state of step-22 about 5% faster.

Initiate an implementation of some of the reordering algorithms using the Boost Graph library. The bandwidth of resulting matrices with their Cuthill-McKee algorithm is often significantly smaller. On step-22, this leads to the fact that the inner solver for the Schur complement, when using the ILU of the Laplace matrix, uses only about 48 iterations in the third refinement cycle, as compared to some 53 or 54 with our own algorithm.
