assignment operator.
This must be implemented by the derived class (with this prototype).
For now, this function is purely abstract. Might there be some members added to this (base) class, then an implementation could be made. This should then be called using PolicyPoolInterface::operator=(o) from the copy assignment operator of the derived class. See also http://www.icu-project.org/docs/papers/cpp_report/the_assignment_operator_revisited.html .
Implements JointBeliefInterface.

Performs a joint belief update on this joint belief.
Performs the belief update. I.e., given the current joint belief b (which is represented by this), we compute P(s'|b, a, o) for all new states s'. This function updates this belief (alter this object). Returned is the normalization factor P(o|b,a), which is also to probability that this new history (belief) occurs given the previous one.
Implements JointBeliefInterface.
