Add a b-spline curve of degree degree with pointTags control points. If weights, knots or multiplicities are not provided, default parameters are computed automatically. If tag is positive, set the tag explicitly; otherwise a new tag is selected automatically. Create a periodic curve if the first and last points are the same. Return the tag of the b-spline curve.
