> 1. We expose all the stuff in data types right now, including NumericTypes, etc. These should be hidden from users. We should only expose the leaf types.
> 2. Remove DeveloperAPI tag from the common types.
> 3. Specify the internal type, external scala type, and external java type for each data type.
> 4. Add conversion functions between internal type, external scala type, and external java type into each type.
