This function returns a matrix containing all probabilities of the policy.
Note that this may be expensive to compute, and should not be called often (aside from the fact that it needs to allocate a new Matrix2D each time).
Ideally this function can be called only when there is a repeated need to access the same policy values in an efficient manner.
Implemented in AIToolbox::MDP::WoLFPolicy, AIToolbox::MDP::QSoftmaxPolicy, AIToolbox::MDP::PolicyWrapper, AIToolbox::MDP::PGAAPPPolicy, AIToolbox::MDP::QGreedyPolicy, AIToolbox::MDP::BanditPolicyAdaptor< BanditPolicy >, and AIToolbox::MDP::EpsilonPolicy.
