    Thanks. I'll clean up the messy commits today. Not sure how it picked up the other six
commits...

> The Parquet record reader class is a key part of Drill that has evolved over time to
become somewhat hard to follow.
> A number of us are working on Parquet-related tasks and find we have to spend an uncomfortable
amount of time trying to understand the code. In particular, this writer needs to figure out
how to convince the reader to provide higher-density record batches.
> Rather than continue to decypher the complex code multiple times, this ticket requests
to refactor the code to make it functionally identical, but structurally cleaner. The result
will be faster time to value when working with this code.
> This is a lower-priority change and will be coordinated with others working on this code
base. This ticket is only for the record reader class itself; it does not include the various
readers and writers that Parquet uses since another project is actively modifying those classes.
