New description:
The Polyhedron class is, so far, free-standing with some sort of coercion
for the base ring tacked manually. This ticket strives to add parents for
polyhedra and make the base ring coercion work more naturally.
There will be 3 supported base rings:
* ZZ (meaning that the polyhedron is a lattice polytope, that is, both
H- and V-representation are defined over ZZ)
* QQ
* RDF
Apply:
* [attachment:trac_11763-polyhedra_coercion_folded.2.patch]
* [attachment:trac_11763_fix_associahedron.patch]
* [attachment:trac_11763_relax_typechecks.patch]

Comment (by vbraun):
The final patch fixes the `point()` command to not make dumb type checks.
