Description
We migrate is_neighborly
and neighborliness
to CombinatorialPolyhedron
.
It is also faster now, as use the fvector instead of indirectly getting the number of kfaces.
Along the way we add is_simplex
to CombinatorialPolyhedron
and cache the methods f_vector
and n_vertices
.

 I would suggest adding the definitions of "kneighborly" and "neighborly" instead of referring to Wikipedia.
 The sentence for the dsimplex is not a definition. It is just an example. So why should it be mentioned?
*
  ``True`` if the every set of up to ``k`` vertices forms a face, +  ``True`` if every set of up to ``k`` vertices forms a face

Small coding style:
+ @cached_method + def neighborliness(self): + r"""  Returns the largest ``k``, such that the polyhedron is ``k``neighborly. + Return the largest ``k``, such that the polyhedron is ``k``neighborly.
You can put this on positive review on my behalf once this is fixed.
