simulation is layered on another.

This is conceptually much cleaner, as it shows that the state is always a pointer.
It also makes it easier to marshall these values around across the internal APIs
of the path-sensitive engine.

allow us to pass the builder to plug-in transfer functions and allow those
functions to create intermediate nodes.

The basic idea is that all these algorithms are computing the longest paths from the root node or to the exit node. Therefore the existing implementation that uses and iterative and potentially
exponential algorithm was changed to a well-known graph algorithm based on dynamic programming. It has a linear run-time.
