We now use a presized HashMap and Weak references in BasicPersistentEntity to improve memory and CPU profile and and avoid unmodifiable collection creation in BasicPersistentEntity.iterator(). Refactored ClassTypeInformation.from(…) lambda to method reference and predefined collection size for the cache. Reduced object instantiations during TypeDiscoverer.equals(…) by checking for type variable map emptiness to avoid Map iterator creation in Map.equals(…). Original pull request: #305.

- Support for cross-store persistence
- Dynamic query generation from query method names
- Implementation domain base classes providing basic properties
- Support for transparent auditing (created, last changed)
- Possibility to integrate custom repository code
- Easy Spring integration with custom namespace
