RAVE-910 - Implemented CXF WS Framework. Created the rave-core-api module and moved all the interfaces from rave-core/org.apache.rave.portal.model into rave-core-api/org.apache.rave.model. This allows them to be used by the rest of the API. A first cut at a User and Person RESTFUL service is in place and accessible at /portal/api/rest/people & /portal/api/rest/users
