Hello and thanks for your very useful library. I implemented it in FreeCAD: [github repo](https://github.com/ebrahimraeyat/PitchedRoof) there is a library called [Pyskeleton](http://vision.mas.ecp.fr/Personnel/teboul/pySkeleton.php) that can take different angles for each edge: [different angles](https://forum.freecadweb.org/viewtopic.php?p=460915#p460915) Can we apply this feature in polyskel? Thanks a lot
