* Removed several itertools recipes now obviated by `more-itertools
<https://github.com/erikrose/more-itertools>`_ (recipes and more):
- grouper -> recipes.grouper
- grouper_nofill -> more.chunked (note parameters are switched)

- pairwise
- consume
- roundrobin
- unique_justseen
- unique_everseen
* Add logging.setup_requests_logging, following the pattern document at
