quickcheck-classes-0.3.3: QuickCheck common typeclasses

This library provides quickcheck properties to ensure that typeclass instances the set of laws that they are supposed to. There are other libraries that do similar things, such as `genvalidity-hspec` and checkers. This library differs from other solutions by not introducing any new typeclasses that the user needs to learn. The source code for this library should be easy to understand if you are already familiar with quickcheck. Open an issue if you feel that this is not the case.
