 8. Fix floating point comparisons in the doctest output.

+10. Sometimes our Lyapunov-like tests over the ice cream cone are
+    failing badly. For example,
+
+  FAIL: test_lyapunov_icecream (test.symmetric_linear_game_test
+                                .SymmetricLinearGameTest)

+
+    We should have a matrix L that is negative stable, but its eigenvalues
+    are actually,

+
+12. Investigate this test failure too. It looks like it was really
+    close to being solved, but we would have needed a fudge factor
+    of three instead of two.
