Merged third commit of pull request #25 from Alexander Wenger.

Comment from the author:
In GUI and plot code an option is implemented to chose the end position of the blade after cutting. This can be useful for some jobs. There was already some code which seemed to be intended for this purpose but was left unfinished. Frankly, I had some difficulties understanding the logic and implemented my own approach.
