First 7 propositions from book 11 more or less work [books11-13.pdf](https://github.com/jemmybutton/byrne-euclid/files/2452035/books11-13.pdf)

Thank you! In the original text this point on the circumference is not referenced directly, instead, it is some unnamed point along BC. I thint it won't do much harm...

Propositions up to XI.XVI are added https://github.com/jemmybutton/byrne-euclid/commit/be907a8b617786f9d856a98a02df0b8bb758c52d At this stage the main focus is not on aesthetics, but rather on getting all the tools working and handy.

Propositions up to XI.XXI are added https://github.com/jemmybutton/byrne-euclid/commit/b6db91f2d46b1eab5b877a97106a6b6fb24d6547 Solid angles look odd. [books11-13.pdf](https://github.com/jemmybutton/byrne-euclid/files/2475580/books11-13.pdf)

I'm not sure even without automation what's the right way in this case, it's horizontal and would be displayed as CB, is this so bad? But anyway, for now i...

Thank you very much! These are fixed (mostly) with this commit: https://github.com/jemmybutton/byrne-euclid/commit/65f086cf1085994504bfb164c9c93af024d4bbfd This is basically the issue of proofreading russian translation, which is to be done, so i will not...
