Modernize makeRefinedSimplexGeometry implementation and test
- This modernizes the implementation by providing support for the new function interface and deprecating the old style interface.
- The tests are updated to now use
Dune::TestSuite
- The failing test is fixed by replacing (now incorrect) hard coded values by computed ones.
I believed that the test failure was introduced by AluGrid permuting vertices during grid creation. This should now be fixed by avoiding hard coded values.
