Comment(by vbraun):

 I don't know yet what to do with quotients, but can we change the
 representation of sublattices to, for example,
 {{{
 sage: L = ToricLattice(3, "L")
 sage: L.submodule_with_basis([(3,2,1),(1,2,3)])
 Sublattice <L(3, 2, 1), L(1, 2, 3)> of 3-d lattice L
 sage: L.submodule([(3,2,1)])
 1-d sublattice of 3-d lattice L
 }}}
 Patch is attached.
