Again, to change a deffacts from the Jess language, you must redefine
the entire thing. Alternatively, you can define a jess.Deffacts object
in Java, and add it to the engine with Rete.addDeffacts(). You could
then add new facts, or change existing ones, in your Deffacts object,
and the changes would be visible at the next (reset) command.
