Comment(by vbraun):
I've updated the reviewer patch accordingly. Now the coordinate vectors
work as expected:
{{{
sage: N = ToricLattice(3)
sage: Ns = N.submodule([N(1,1,1), N(1,2,3)])
sage: Q = N.quotient(Ns, positive_point=N(0,0,-1))
sage: Q.gen(0)
N[0, 0, -1]
sage: Q.gen(0).vector()
(1,)
sage: Q(0,0,-1)
N[0, 0, -1]
sage: Q(0,0,-1).vector()
(1,)
sage: q1 = Q(1,0,0)
sage: q1
N[1, 0, 0]
sage: q1.vector()
(-1,)
}}}
