1New: FEEvaluation::evaluate(), FEEvaluation::integrate(),
2FEFaceEvaluation::evaluate() and FEFaceEvaluation::integrate() now take an
3argument of type EvaluationFlags::EvaluationFlags to determine which of the
4values, gradients or hessians should be evaluated to quadrature points or
5integrated, allowing much more expressive programs than the previous list of
6bools. The evaluation flags can be combined with `operator|`, similarly to
7UpdateFlags for FEValues.
