lattices-2.2.1: Fine-grained library for constructing and manipulating lattices

In mathematics, a lattice is a partially ordered set in which every two elements x and y have a unique supremum (also called a least upper bound, join, or x \/ y) and a unique infimum (also called a greatest lower bound, meet, or x /\ y).

This package provide type-classes for different lattice types, as well as a class for the partial order.
