Initial implementation and tests for JIRA feature requests SGF-207 and SGF-254 supporting inheritable Region templates when defining GemFire Regions using Spring Data GemFire XML configuration meta-data. This feature allows common Region configuration and attribute values to be defined once and then shared across multiple Region bean definitions in the Spring context for added convenience.
