Started with test decision JSON objects.
Added new Policy Finder Factory that ONAP will use and got the code working with new policy/models (see other review which will have to be merged first). Added some new conversion methods to convert from a Xacml request to an Onap request. Added some property methods for XACML Properties objects and JUnit tests. Started filling in some Guard application details and combining code. Issue-ID: POLICY-1602 Change-Id: I5235b74f3b036dcf05779b655a03ac290d594354 Signed-off-by: Pamela Dragosh <pdragosh@research.att.com>
