/**
 * Additional BusinessRuleTask support that allows to decouple rules from processes - as default BusinessRuleTask
 * uses exact same working memory (kie session) as process which essentially means same kbase.
 * To allow better separation and maintainability BusinessRuleTaskHandler is provided that supports:
 * <ul>
 * <li>DRL stateful</li>
 * <li>DRL stateless</li>
 * </ul>
 * <p>
 * Session type can be given by KieSessionType data input and session name can be given as KieSessionName property -these apply to DRL only.
 * <p>
 * Results returned will be then put back into the data outputs. <br/>
 * <br/>
 * DRL handling is based on same names for data input and output as that is then used as correlation.<br/>
