I had thought about the possibility that the order of
the faces (in the Brillouin zone code) was random, and
also that a face could be returned with points in
reversed order (i.e., upside down); but the test to check
this case had a bug (that probably was never spotted
because until now the order was the same as in my test).

This fixes #78
