## Detailed Description

Perturb a curve.

This tool perturbs all the points of a given "closed" PKF curve. The perturbation takes place in the plane that is normal to the tangent vector at the point to be displaced. The angle is in the interval [0,2 pi] and the magnitude is randomly chosen according to the scaling factor given as an input.
