[PythonCAD] Offline for a short while

[Art Haas]

Hi.

I'll be offline again for about the next ten days. Also, I'd hoped to
have sent more changes to the repo for dealing with the quadtree changes
of last week, but I did not get things to a point where I felt that
sending them out would be wise. Handling the possibility of numerous
equivalent entities in a drawing is more involved than I'd hoped.
