Detailed Description
BayesianGame is a class that represents a general Bayesian game in which each agent has its own utility function.
This is a self contained class: meaning that it does not depend on any Multi-agent decision problem or Planning unit. This implies that, in order to convert a time-step of a MADP Planning Unit to a Bayesian game, indices of observation(-action) histories have to be converted. This class uses its own indices.
