This package provides families of lenses, isomorphisms, folds, traversals, getters and setters.
These lenses are compatible with those from lens-family, lens-family-core and lens-family-th, but they provide a great deal of additional flexibility in their composition.
An overview of the derivation of setters, folds, traversals, getters and lenses can be found on the lens wiki under Tutorial.
