Module documentation for 0.12.8

Used by 2 packages in nightly-2016-06-26(full list with versions):
classy-prelude-conduit, classy-prelude-yesod

Modern best practices without name collisions. No partial functions are exposed, but modern data structures are, without requiring import lists. Qualified modules also are not needed: instead operations are based on type-classes from the mono-traversable package.
