> The current row set readers have incomplete support for hyper-vectors. To add 
> full support, we need an interface that supports either single batches or 
> hyper batches. Accessing vectors in hyper batches differs depending on 
> whether the vector is at the top level or is nested. SeeĀ [this 
> post|https://github.com/paul-rogers/drill/wiki/BH-Column-Readers] for 
> details. Also includes a simpler reader template: replaces the original three 
> classes with one, in parallel with the writers.
