I think the changes are good! Thanks for working on this. ð
As a final change before merging, I would annotate the new classes/methods
as `@PublicEvolving`, would you be ok with that? And I would also like to
change `SessionWindowTimeGapExtractor.extract()` to return a long instead of
`Time`. What do you think?---
