Comment:
I fixed a number of cases where Symbolic Ring was being returned by
changing how the conversion was being done and not doing the (unnecessary)
division in the [0,1] case.
There are still some obscure cases where we can't get back from the
Symbolic Ring. Such as certain maps where the coordinate ring is a
function field over QQbar.
