I added a missing BSD licence to the distribution


This used to be licensed BSD. Has that changed? I can't find any licensing information here or on Github. Thanks!

Hey Enrico,

many thanks for the fast reply. Looking forward to see it! : )

Thanks for the effort : )

Best regards,

Simply no, you are asking for G2 fitting. I am working on G2 fitting, I will put the software on ``File Exchange'' when finished.

Is there a way you have a specific curvature in the end of the clothoid? E.g. if I like to let it combine a straight line with a circle.

Many thanks in advance,

Thanks for the code. Will rate it after using it for a little while.
