Comment (by ptigwe):

 In the examples for the `best_responses` function, the second example for
 the second player actually calculates the best response for the first
 player.

 {{{
 sage: g.best_responses((1/2, 1/2), player=0)
 }}}

 Also, I think a value error should be raised when `player` is greater than
 1. Currently the following happens.

 {{{
 g = NormalFormGame([matrix.identity(3)])
 g.best_responses([1, 0, 0], 2)
 .....
 UnboundLocalError: local variable 'payoff_matrix' referenced before
 assignment
 }}}
