Introduce Supervisor, extract evaluation-related stuff from Program, merge with EvaluationFeedbackHandler.
Move implementation of EvaluationFeedback to internal API, reduce number of public interfaces.
Cleaner interface for reporting feedback.
Switch Dispatcher to use tag as Rule's unique identifier.
De-couple RuleMatcherImpl from the Rule instance.
Rule instances are externally provided, and in case of incremental
Program update these will be all replaced with new ones.
Better to keep loose coupling between those and the reactor implementation.
