@StephanEwen , I have created a separate function to create type
information for 2-tuple.
One question though. Why is there a need to generate type information
explicitly here? The `TypeInformationGen` class does have a case analysis for
`Product` types. I may be very wrong, but `createTypeInformation` macro cannot
be used anywhere inside the module itself but only after the module's been
compiled. This is perhaps why `createTypeInformation` works in, say,
`flink-ml`.
