Add SDNC naming application
Requires changes to StdMatchableTranslator to go deeper when searching for matchable attributes. NOTE: will re-visit the StdMatchableTranslator at a later date in order to support more robust Policy Types. And document best practices for defining matchables. Issue-ID: POLICY-1740 Change-Id: I291cf1c2e6eba0a677a3312dd11f0e56178a805b Signed-off-by: Pamela Dragosh <pdragosh@research.att.com>
