Starting point

This lesson runs in the lab from lesson 1. Lesson 1's two files in src/lab/ can stay, since nothing in the game imports them.

Lesson 1 found the push line and the depth. A push also needs a place to land. Lesson 1.6 measured the lever arm from the deepest corner. This lesson is about whose corner that is, and what happens when two corners are equally deep.
