生成螺旋形的球体线条，还有经度线，乱线三种效果

(203)制作螺旋线物体及生长动画的小玩意~

新螺旋线，它不像默认的普通螺旋线，它默认只有4个顶点，方便曲线调节，如果有需要，也可以调节参数，生成更多的顶点。 如下图对比，左边是默认的MAX螺旋线，右边是新螺旋线。 Just like the regular helix only with four bezier handles per turn (or more if you would like - you can control that with the Steps spinner) instead of 40 corner-points of the default Helix shape.

超级螺旋，示例的是螺旋风管，螺纹，金属软管，环形坡道等的制作方式，可以支持自定义形状。Example usage would be spiral ductwork, screw threads, flexible metal tubes, circular ramps etc. No smoothing groups are assigned, for smooth look either use Smooth modifier or add points to the spline profile.
