> An appealing case for the Jena Rules Engine is to use rules to trigger a set of actions in the rule heads that create side effects in the Java Universe:  consider (1) constructing and populating Java data structures in the rule head,  and (2) use of the rules engine in a "reactive" scenario where changes in the outside world are inserted into the graph as facts,  triggering actions on a distributed system in the heads.
> In cases like this,  the creation of a new set of built-ins could occur somewhat frequently so efficiency matters here so I don't like the idea of this registered in some central registry so that we can pass in the built-in parameter with the resource to the factory,  so the advised method for configuration is to add a setter on the GenericRuleReasoner,  The only concern I have is "order-of-operations" involving initialization,  etc.
