Parametric curves

[Ottia Tuota]

I shall take it as a habit to write the history. I am a newcomer, and even writing lots of comments in the code is something I had to learn just to be able to develop my own code later.

You are trying to put the custom parameter values in the GUI as a list. That is something I did not come to think of. The format is just the values separated by commas. I shall see if I can make it to accept both ways. But not today, perhaps tomorrow.
