the fantastical wizard monoid.

A "wizard" can be defined as a program that prompts a user "up front" for multiple inputs and then performs several actions after all input has been collected. The idea is from Gabriel Gonzalez's blog post, http:/www.haskellforall.com201802the-wizard-monoid.html. This library provides a WizardT monad transformer, that allows users to define wizards over different monads, which becomes similarly useful when that monad's Monoid instance lifts the behaviour of the underlying Monoid into its own.
