{{{
sage: p = Polyhedron()
sage: p
The empty polyhedron in QQ^0.
sage: p.contains(0)
True
sage: p.contains(1)
True
sage: p.contains([0, 1])
True
sage: p.contains([(0, 1)])
True
sage: p.interior_contains([0, 1])
True
sage: p.relative_interior_contains([0, 1])
True
}}}
I think all of the above should return False.
