===== Usage =====

This is a simple, dynamic and customisable curved line based on Bezier curves. For informations about the meaning and the usage of the control points check http://pomax.github.io/bezierinfo/

Sample:
<code objc>
self.curve = [[SXBezierCurve alloc]initWithStartPoint:[SPPoint pointWithX:0 y:0]
                                                            endPoint:[SPPoint pointWithX:0 y:100]
                                                       controlPoint1:[SPPoint pointWithX:100 y:20]
                                                       controlPoint2:[SPPoint pointWithX:80 y:80]];
    self.curve.x = 300;
    self.curve.y = 100;
    self.curve.color = SPColorNavy;
    self.curve.thickness = 5;
    [self addChild:self.curve];
