Algebra.Monoid

Will be used in order to generate type classes for generic algebras. An algebra is a vector space that also is a monoid. Should we use the Monoid class from base library despite its unfortunate method name mappend?

Documentation

class C a where

We expect a monoid to adher to associativity and the identity behaving decently. Nothing more, really.
