* Reorganizing packages and dependencies to support standalone subscription running within a CDR container where all hapi modules are on the classpath.
* EXPERIMENTAL: Moved Subscription registry out of interceptor and introduced ISubscriptionLoader that will be either a Database or FhirClient loader.
5 tests fail. Looks like we're getting too many matches--likely because there is now just one list of subscriptions instead of one list per interceptor.
* Created ActiveSubscription and moved cache bits into it
* Compiles. Next step is get app context to load.
* Application context loads. Now fix NullPointer.
* All subscription tests pass
* FIXME cleanup
* jpa-subscription tests
* fixed config so other module tests work
* MAJOR MILESTONE: All hapi-fhir tests pass.
updated READMEs in example projects
