GSoC Week 11 Recap

Unfortunately, it looks like solid, usable improvements to the Attachment Editor are unlikely to be ready for a PR by the end of my GSoC, although I will publish my experimental branch which uses Python for the datum tools and uses the Python-based Attachment Editor I mentioned previously.

However, as a consolation I did finalize some additional tests for PartDesign Hole, so my goal of functional coverage of the PartDesign tools succeeded.

Also, I think with this foray into GUI code, I've hit nearly the full stack of libraries used in FreeCAD this summer. It feels pretty nice, because I feel prepared to tackle whatever problem I want to in the FreeCAD project.
