CubicBezierCurve(java.awt.geom.Point2D[] ctrlPnts,
                 int l)
```
    Constructor of CubicBezierCurve
    
    Parameters:
    
    ctrlPnts - 4 control points [p0, p1, p2, p3]
    
    l - dividing level, if l = 0, one cubic Bezier curve is divided into 2^0 = 1 segments, if l = n, one cubic Bezier curve is divided into 2^n segments
