This Haskell package implements naive type level integers. It exposes
the module Data.Type.Integer which exports a new kind LiftedInt
populated by the types Z (zero) and LInt Sign PosNat. In other
words, a (type level) integer is either zero or a positive natural
number together with a sign.
The module exports the type families LIntSucc, LIntPred,
LIntInvert, LIntPlus and LIntMinus for manipulating types of
kind LiftedInt.
