Just to make sure I understand, semantically here, there is nothing special
about a line sequence, it's just an optimization to let LineTable know
you're giving it sorted values?  So any lines you add via a LineSequence,
could also be added individually with insertLine, but it would be slower?
And aside from that everything else would still work as expected?
