Updated and extended documentation
Enabling NoImplicitPrelude language extension

Imports changed to not use Prelude module.
Renaming <@> to ~@~, <@@> to ~@@~, <$@> to <~@~, and <@@$> to ~@@~>

Using <@> and <@@> caused colision with comonad package
(http://hackage.haskell.org/package/comonad) and Hayoo wasn't able to
find anything named ~@~ or ~@@~.
Version bumped to 0.9.0.0; updated package description
Updated README with the same text as is in Cabal file
