The attached patch enables ``&`` and ``in`` operators for polyhedrons::
{{{
sage: cube = polytopes.n_cube(3)
sage: oct = polytopes.cross_polytope(3)
sage: cube.intersection(oct*2)
A 3-dimensional polyhedron in ZZ^3 defined as the convex hull
of 12 vertices
sage: cube & oct*2
A 3-dimensional polyhedron in ZZ^3 defined as the convex hull
of 12 vertices
}}}
{{{
sage: P = Polyhedron(vertices=[[1,1],[1,-1],[0,0]])
sage: P.center() in P
True
sage: [-1,-1] in P
False
}}}
