Changelog for decidable-0.3.0.0

Changelog

Feburary 2, 2020

Update to work with singletons-2.6, the type family update
Change Evident to now be a defunctionalization symbol for Sing, instead of a type synonym with TyPred, to match with singletons-2.6. Most code in practice should be the same.
Fix instances for FProds: now can prove and decide any FProd f (Wit p), and can prove and decide and auto any FProd f WrappedSing.

October 29, 2018

Added tripleNegation and negateTwice to Data.Type.Predicate.Logic, for more constructivist principles.
Renamed excludedMiddle to complementation.
Add TyPP, SearchableTC, searchTC, SelectableTC, selectTC to Data.Type.Predicate.Param, to mirror TyPred and the DecidableTC/ProvableTC interface from Data.Type.Predicate

October 24, 2018

Added a type and Universe for universe disjunction or summing, :+:, with appropriate Elem and Auto instances.
Added Universe instances (and appropriate Elem and Auto instances) for Proxy (the null universe) and Identity.
Auto instances for IsNothing and IsLeft.

October 14, 2018

New :.: for universe composition, with Elem and Universe instances, and associated functions for working with them alongside Any, All.
Many of the Elem instances and indices in Data.Type.Universe have had their name changed to be more consistent with their role as indices. IsJust is now IJust, IsRight is IRight, Snd is ISnd.
Convenience predicates for alternate universes, such as IsJust, IsLeft, IsNothing, etc.
NotAll quantifier added alongside None.
Many new implications added to Data.Type.Predicate.Quantification, converting not-any and all-not, etc.
NotFound p added as a convenience predicate synonym for Not (Found p).
Some implications showing the equivalence between Found (InP f) and NotNull f added to Data.Type.Predicate.Param.
Many new deduction rules added to Data.Type.Predicate.Auto. Please see module documentation for a detailed list of new rules and classes in this version.
Convenient combinators for dealing with Refuted and Decision added to Data.Type.Predicate: elimDisproof and mapRefuted.

October 12, 2018

flipDecision, forgetDisproof, forgetProof, isProved, and isDisproved added to Data.Type.Predicate module.
ProvableTC, DeccidableTC, proveTC, and decideTC helper functions and constraints
Data.Type.Predicate.Auto module, for generating witnesses at compile-time.
Instances for injection and projection out of &&& and |||, with some tricks to prevent overlapping instance issues.
