Possible documentation typo in "Cross evaluating random players" example

[KierranFalloon]

Just a small one, but in the "Cross evaluating random players" documentation, the note near the top reads:
"This example uses tabulate ti format results. You can install it by running pip install tabulate."
Perhaps "ti" is meant to read "to"?

Good catch. I fixed it in d6b07d8 - thanks!
