Polyline approximation with arcs and segments.

A routine for fitting an unknown sequence of circular arcs and segments to an indexed set of dots.

This code is related to the method described on the publication "Polyline defined NC trajectories parametrization. A compact analysis and solution focused on 3D Printing." by Honorio Salmerón Valdivieso.
It also makes direct use of the code published by Taubin in https://es.mathworks.com/matlabcentral/fileexchange/22678-circle-fit-taubin-method

It simply finds an efficient distribution of arcs matching some tolerance requirements and merges them with the source polyline.
