Comment:
Passes tests and allows creation of ideals within rings of integers mod n.
But it seems the resulting ideals still need some work, for example
{{{_contains_()}}} in {{{rings.ideal.Ideal_generic}}} is not implemented.
{{{
sage: R=Integers(40)
sage: Q=R.ideal([2,3])
sage: type(Q)
<class 'sage.rings.ideal.Ideal_generic'>
sage: 1 in Q
