Can we remove the confusing comment `"abstract methods allow for multiple
table and scanners in the same job"` and add JavaDocs to all abstract methods
that describe what is expected from their implementation?
A `TableInputFormat` instance should only scan a single table. In case more
tables need to be read, each could be read with a separate `TableInputFormat`
instance and the output of those could be unioned if needed.
