Some of the #include files you have listed above directly or indirectly
already had an
#include <deal.II/fe/fe_values.h>
somewhere. But it is useful to have it in your file anyway, just to be sure
and because you don't want to depend on whether or not one of the deal.II
files already #includes it or not.
