Could you please provide a link?

Could you please provide source code? What are these integar tags
used for?

I remember reading somewhere it could be used in a gaming application
to code what happens when, for example, to opposing space warships
do battle in space. Another toy use case it to decide what happens
when two animals meet. (e.g. Dog chase cat. Cat eats mouse,)

Using your library, how would you code the predator_prey.cpp example
shown here:
