Produce URS using `hashtocurve` logic. 2021-02-22 15:50:01 -07:00
Jack Grigg b4ed5295fe Migrate to group traits 
The `Curve` trait is now `CurveExt: group::prime::PrimeCurve`, and
`CurveAffine` is now `CurveAffine: group::prime::PrimeCurveAffine`.

There is no `CurveAffine` trait in `group`, and it's a widely-used
trait in this crate, so we don't rename it to `CurveAffineExt`.

Jack Grigg 82da677add Add name field to ConstraintSystem::create_gate

do not require any runtime information to name.
