    Description
    Fold<S,A>
    A Fold can be seen as a Getter with many targets or a weaker PTraversal which cannot modify its target.
    Getter<S,A>
    A Getter can be seen as a glorified get method between a type S and a type A.
    Iso<S,A>
    PIso when S = T and A = B
    Lens<S,A>
    PLens with a monomorphic set function
    Optional<S,A>
    POptional restricted to monomorphic update
    PIso<S,T,A,B>
    A PIso defines an isomorphism between types S, A and B, T:
    PLens<S,T,A,B>
    A PLens can be seen as a pair of functions: get: S => A i.e.
    POptional<S,T,A,B>
    A POptional can be seen as a pair of functions: getOrModify: S => T \/ A set : (B, S) => T
    PPrism<S,T,A,B>
    A PPrism can be seen as a pair of functions: getOrModify: S => T \/ A reverseGet : B => T
    Prism<S,A>
    PPrism restricted to monomorphic update
    PSetter<S,T,A,B>
    A PSetter is a generalisation of Functor map: map: (A => B) => F[A] => F[B] modify: (A => B) => S => T
    PTraversal<S,T,A,B>
    A PTraversal can be seen as a POptional generalised to 0 to n targets where n can be infinite.
    Setter<S,A>
    PSetter with a monomorphic modify function
    Traversal<S,A>
