code: public static Matrix4d superposeAtOrigin(Point3d[] fixed, Point3d[] moved) {
  		superposer.setCentered(true);
  		return superposer.superpose(fixed, moved);
  	}
docs: Use the {@link SuperPosition#superpose(Point3d[], Point3d[])} method of
  the default static SuperPosition algorithm contained in this Class,
  assuming that the point arrays are centered at the origin.
