aux_stochastic has a problem

[TheodoreEhrenborg]

One of the algorithms that I wanted to include assumed that the game was symmetric, and then tried to maximize the points earned this round. Theoretically this task should be handled by round_points. But roundpoints tends to assume that all players settle on one strategy each, but pure strategies generally aren't feasible. I need symmetric versions of the three round strategies of aux_stochastic. But this issue can wait.

This is a limitation that I should talk about in my conclusion.
