Smoothing Cubic Splines with periodic conditions

Implements a model for Cubic Smoothing Splines with periodic boundary conditions

You are now following this Submission

Smoothing cubic splines are implemented with periodic conditions, so that closed curves in any dimension can be approximated. It includes a test function to demonstrate it.
Theoretical arguments supporting this implementation can be found here:
