* @class CubicBezier
* @sbmlbrief{layout} A %CubicBezier represents a smooth curve in the
* “layout” package.
*
* In order to be able to represent smooth curves the “layout”
* package defines the class CubicBezier. It represents a Bezier curve, and
* is readily available in most graphics APIs. The class CubicBezier is
* derived from LineSegment. It consists of four elements: the two inherited
* elements 'start' and 'end', which specify the starting point and the
* endpoint of the cubic bezier curve, and two elements 'basePoint1' and
* 'basePoint2', which specify the two additional base points that are needed
* to describe a cubic bezier curve.
