A class to draw a CatmullRom curve.
This class allow to draw a CatmullRom curve, a smooth curve which passes through all its control points. CatmullRom splines are a family of cubic interpolating splines formulated such that the tangent at each control point is calculated using the previous and next control point point of the spline. CatmullRom splines have C^1 continuity, local control, and interpolation, but do not lie within the convex hull of their control points.
