It doesn't make sense to ask for the value of a slot in a template --
template-slots don't have values any more than the members of a class
in Java have values. In Java, only the members of *objects* have
values. In Jess, only Facts have slot values. Facts are instances of a
template in the way that objects are instances of a class.
Now, given that, being notified when Facts change is what Jess is all
about. You write a rule which matches the Facts of interest, and on
the right-hand-side you take whatever action you want to take when the
pattern is matched. Whenever the right facts exists, Jess fires the
rules.
