Created a SimpleEnum entity that can be reused amongst classes; simplified a couple of tests
Moved index tests into their own package, simplified into just three tests and pulled out a) general entities that could be used for testing elsewhere and b) any tests that were not index-specific
Moved version test in VersionedUpdateTest into the more general TestVersionAnnotation class
Moved TestLargeObjectsWithCursor from its poor lonely package up to join the other tests
Simplified MorphiaLoggerFactoryTest
