> Thus far Quickstep has required column stores to be sorted, even though sorting is really orthogonal to the layout of attribute data in a block. BasicColumnStoreTupleStorageSubBlock should make sorting an optional, rather than a required feature.
> In the long term, it would be nice to allow any tuple store to be sorted or unsorted as we please, but doing that right will require a more extensive refactor.
