4. Come up with a fast heuristic (like making nu huge and taking e1 as
our point) that finds a primal feasible point.
-5. Fix the solve failures that we get in the translation tests. For example,
-
- ERROR: test_translation_orthant (test.symmetric_linear_game_test.
- SymmetricLinearGameTest)

-8. Fix floating point comparisons in the doctest output.
+5. Add a test to ensure that if we solve the same game twice, we get the
+ same answer back.
