Improved Network Structure

To allow for belief updating in a more complex Bayesian network to be implemented easily, the original version of BPP, written in LISP, was rewritten and ported to C++. This conversion allowed for the use of the Netica API [NorsysNorsys] for constructing and manipulating complex belief networks. The limitations of the previous version also restricted the previous network to a polytree form, which did not allow for an accurate representation of all influences and dependencies, as the method of belief updating used could not be easily adapted to fit a more complex network.
