Circular switches

[lizliz]

Description

I added a drawing ability to see the angles where two vertices switch order. This is useful for some theoretical projects coming down the pipe.

Added a function to the EmbeddedGraph class called get_all_angles which gets all the angles of the line normal to the line segment between every pair of vertices. Added an option to the plotting command, angle_labels_circle=True, which will draw these things on a circle around the graph (as long as it's not too big). Added a jupyter notebook with basic examples of these called Tutorial-ExactECT.ipynb.

Motivation and Context

Fun to play with for future projects.

How has this been tested?

Added a small test for the output of the angles function.

I had some dumb merging issues @Yemeen so I'd appreciate you checking this out for me :D

Sorry, not ready yet. Just was staring at the picture and it's drawing things in the wrong places. I'll fix it and re-request.

Now the drawing looks like this. Also added some better tests.
