title: Find bezier control-points for curve passing through N points
body: <p>Considering the following nice solution for finding cubic Bézier control points for a curve passing through 4 points:</p>

  <p>I wonder, if there is a straightforward extension to this for making the Bézier curve pass through N points, for N > 2 and maybe N ≤ 20?</p>
