Add a function for projecting points onto reference cells.

This can replace GeometryInfo::distance_to_unit_cell() and
GeometryInfo::project_to_unit_cell() in most circumstances.

There is no clear way to define the infinity norm for sloped surfaces (like the
top face of a tetrahedron), so this new function uses the Euclidean norm.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
