Policy search web service for claim system integration

The WS-I web service CCPolicySearchIntegration web service in the package gw.webservice.pc.pc800.ccintegration replaces the deprecated RPCE web service of the same name. In addition to the change from RPCE to WS-I, the retrievePolicy method changed to return an object of type Envelope instead of type CCPolicy. The type Envelope is an example of an XSD type that encapsulates a type from within PolicyCenter for exchange through web services with claim systems.
