Compute a non rational circular arc (bspline form) passing through two given points.
The degree of the created arc can be linear or cubic and is controlled using the attribute "degree". The number of spans of the curve can be controlled using the attribute "sections".
The radius of the arc can be specified using the attribute "radius". The radius must be atleast half the distance between the two points.
The created arc available at "outputCurve" is non-rational.
