- Added new annotation which can only on a field or property of type
Integer or int
- Only one such field can exist per class
- On read, mapped the generation value back to the field
- On write, if the field is set > 0, set the writePolicy.generation to
this value and writePolicy.generationPolicy to EXPECT_GEN_EQUAL
- Added appropriate configuration file
- Added code config: `.withFieldNamed("generation").asGenerationField()`
- Created unit tests for validation
- Updated the AeroMapperBaseTest class to honor `test.host` if set as a
system property instead of the default `localhost:3000`

@AerospikeGeneration instead of @Version

If for some reason, the class's write policy is set to GenerationPolicy.EXPECT_GEN_GT will we be overriding it?

Yes. I have never found any reason to use EXPECT_GEN_GT, it makes no sense as generations wrap around.
Good catches on those couple of trailing references to version instead of generation!
