Description
We change the mappings used in method is_planar from file planarity.pyx to avoid calls to .vertices().
The changes done here were inducing a doctest error in method genus for
sage: cube.genus(circular=['01','10'], on_embedding=True)
As the documentation indicates that "If circular is defined, on_embedding is not a valid option", we now raise an error.
