New description:
It would be nice if roots of quadratics printed using the quadratic
formula in QQbar, i.e.,
{{{
sage: QQbar(sqrt(2))
sqrt(2)
}}}
Additionally, it would be nice if we could wrap qqbar elements as SR
objects.
The first patch just affects printing of qqbar elements. The second lets
you do more than just print (e.g., SR(QQbar(sqrt(2))) should give you
sqrt(2), not just print sqrt(2))
