> ExternalSortBatch provides a spillable sort operator for Drill. The code works fine, but can be a hard to follow and understand. Make the following changes to improve ease-of-use for developers:
> 1. Refactor the large methods into bite-sized chunks to aid understanding.
> 2. Provide additional explanation of the theory and operation of this operator.
