+/**
+ * Filesystem Rule Evaluator to support Scenarios.
+ * <p>
+ * Low level operations (create, update, delete etc) are passed into the RuleEvaluator.
+ * <p>
+ * The RuleEvaluator is configured with a list of Scenarios which process the operations as and 
+ * when their patterns match.
+ * The RuleEvaluator evaluates the stream of operations and returns commands to execute.
+ * <p>
+ * The Command Executor executes the commands returned from the RuleEvaluator.
+ * <p>
+ * Each Scenario is a Factory for A ScenarioInstance.  The RuleEvaluator contains a set of active scenario instances.
+ * <p>
+ * @since 4.0
