Hi Peer
>> One general potential problem is that the input currently accepts a list of curves, but it seems like the cornersList approach will only work for a single joined curve.

I wanted to keep it simple, this code is supposed to work just on a single curve.
I know I can fillet corner points of a curve, using a list of true/false values.
What I don't understand is why it won't work on for example an open curve with one corner point. (a V shape curve)
It actually needs a list of two (or more?) to work, while the generateVertices() method returns one vertex.
