Description
Provides the "version 3" scan framework (which can also be thought of
as EVF version 2).
Implements the details of the scan lifecycle for a set of readers,
primarily the process of resolving the scan output schema from a variety
of input schemas, then running each reader, each of which will produce
some number of batches.
Version 3 of the text reader.
