could you please provide PoseGenerators::NurbsMotion

When I developed the library I had to decide if I want to implement nurbs or b-splines. I decided for b-splines (probably because it was easier). So I think a Nurbs pose generator would be a great addition to this libaray and I would happily accept a PR for it. However, I am currently not implementing new features for this library (only bug fixes)
