Provides some documentation and usage information.
Moves monads -> monad for consistency.

rename : src/monads.ls => src/monad.ls
Fixes documentation.
Uses Int instead of Any, and fixes computations.

We can't use ++ because LiveScript optimises (a ++ b ++ c) to a.concat(b, c), which makes sense with Arrays, but not with algebraic semigroups. We were also rebinding the list parameters, which lead to non-working stuff, of course.
Uses Int, since Any takes too long to compute.
Fixes the order of .map operations in the functor law.
Adds tests for monads laws, and an example implementation of the Identity container.
