In the derivation you might already noticed some "rules" for Bézier curves:
 * The polynomial degree is also the degree of the curves.
 * If you need $$n$$ turns, you need at least a $$n+1$$ degree Bézier curve.
 * A Bézier curve always begins tangentially to the line between the startpoint and the first control point (and ends tangentially to the line between the last control point and the endpoint).
