> As of right now the processing in StructBatchReader is as follows:
> * `nextBatch` method : Perform directly on the children with the assumption that the rootReader has no nulls.
> * `seek`, `skipRows`, `startStripe` methods: Operate on the rootReader
> Propose that the StructBatchReader be made consistently to operate on the children and never on the rootReader.
