> The existing RulesEngineService allows for centralized execution of rules, 
> but there may be cases where processors (or other calling components) want to 
> operate directly with an instance of an engine (to prevent a bottleneck with 
> the controller service) or would like access to the rules driving the engine. 
>  To facilitate this a RulesEngine and RulesEngineProvider interface should be 
> created to support the following:
> *RulesEngine:*
>      Firing rules with provided facts and returning required actions 
>      Checking rules with provided facts and return information on which rules 
> were fired from the available list
> *RulesEngineProvider:*
>      Return an instance of a rules engine
