Make anisotropic quadrature order possible for non DG examples.

This did not work previously, since we are patching the submodules, which
makes them dirty, and then `git submodule update` will refuse to update them.

Closes #96.

- Use TensorProductElement in one example.

- We still use the sumfact option to swicth to the sum factorization
  code branch. This way it is still possible to easily swicth between
  sumfact and non sumfact code.

- Only TensorProductElements with the same degree in all directions
  will work. Anisotropie and adaption of quadrature rule will happen
  in the next commits.

These are broken, see !98.

The y ar enot properly implemented right now, do not seem
to be necessary and conflict with recent changes in loopy.
