Support GHC-8.2.1
Fix Template Haskell derivation with non-default type renamer.
Add Recursive and Corecursive Natural instances, with Base Natural = Maybe.

Add Data.Functor.Foldable.TH module, which provides derivation of base functors via Template Haskell.

Renamed Foldable to Recursive and Unfoldable to Corecursive. With Foldable in Prelude in GHC 7.10+, having a needlessly conflicting name seemed silly.
Add support for GHC-8.0.1
Use Eq1, Ord1, Show1, Read1 to derive Fix, Nu and Mu Eq, Ord Show and Read instances
Remove Prim data family. ListF as a new name for Prim [a], with plenty of instances, e.g. Traversable.
Export unfix
Add chronomorphisms: chrono and gchrono.
Add distGApoT
