Added Jack Poulson's choice to the include directory.

Added unit-compliant graph norm to StokesBackwardFacingStepDriver.
Added boundary cell checking for cells without a sideIndex argument.
Revised unit-compliant norm to eliminate q scaling and apply unit compliance to boundary terms.
Added switchover to p-refinement to the basic RefinementStrategy::refine(), once h is too small.
Added some experimentation with conditioning and a new test norm for confusion.
Added CLI specification of Newton-Raphson tolerance.
