sample scala problems to cover in cats docs?
  1. Handling stacked monads and the like e.g. List[Option[T]], `Future[Option[T]``
  2. Referentially transparent error handling
  3. Error accumulation/'parallel' validation
  4. Adding together Option[T]s (a la http://stackoverflow.com/a/16319667, not sure how to word this well)
  5. More explicitly typesafe collections (e.g. non-empty, guarantee that list.head never throws, etc)
