Changelog for package acts

0.3.0.0 ( February 16, 2020 )

• Switch to using the groups package for the definition of the Group typeclass, splitting off the generic instances to the groups-generic package.

0.2.0.0 ( February 14, 2020 )

• Remove definition of cyclic groups. It is instead suggested to use a library which defines modular arithmetic.
  For instance: type C (n :: Nat) = Sum ( Finite n ), using the finite-typelits library.

• CyclicEnum newtype changed to Finitely newtype, which uses Finitary instead of Bounded + Enum. This ensures that the action is by a semigroup of the right cardinality.

• Remove Act instances for Max, Min to avoid possible overlap with user defined instances.

• Add anti :: Group g => g -> Dual g function to construct elements in the opposite group.
  Obsoletes the Act instance for Dual (now removed).

• Address a limitation of GHC < 8.10 with DerivingVia and MultiParamTypeClasses, by manually writing some instances.

0.1.0.0 ( February 13, 2020 )

• Initial release.
