Module documentation for 0.6.0.4

Proof
- Proof.Equational
- Proof.Propositional
  - Proof.Propositional.Empty
  - Proof.Propositional.Inhabited

Depends on 5 packages(full list with versions):

base, containers, template-haskell, th-desugar, void

Used by 4 packages in lts-17.2(full list with versions):

ghc-typelits-presburger, singletons-presburger, sized, type-natural

A simple convenient library to write equational / preorder proof as in Agda. Since 0.6.0.0, this no longer depends on singletons package, and the Proof.Induction module goes to equational-reasoning-induction package.
