> Objectives are:
>  # Encapsulate Ranger policy evaluators into a class (PolicyEngine)
>  # Separate Ranger Policy Engine APIs based on their users (plugin or ranger-admin), and define corresponding wrapper interfaces (RangerPolicyEngine and RangerServicePoliciesAdmin). Provide their respective implementation classes.
>  # Remove unused functionality (keeping usage-counts, re-ordering policy-evaluators based on their usage, etc.)
>  # Separate out request preprocessing into a separate interface (RangerAccessRequestProcessor) which wraps context-enrichers and roles for pre-processing/enriching access request.
>  # Optimize Trie for incremental changes (adds/deletes)
>  # Assorted code clean-up.
