Apache Avro custom LogicalType

This is reference project/template to understand how to define a Custom LogicalType along with Conversion.

TODO:

1. Autogenerate Avro java classes with Converion in built
2. Identify if we need to use velocity templates at all
3. Write detailed post.

USAGE:

1. gradle clean build
2. Run AvroExample (This has the main method)
3. This created a query.avro file. Use java -jar avro-tools-1.9.1.jar tojson query.avro to look at the data in the file.

NOTES:

1. Notice the commented out part in build.gradle - The Autogenerated java class does not have the method to get the conversion.
