--Requirements-- Markov.hs uses: import Data.MarkovChain (run, runMulti) this requires the package markov-chain from hackage install with 'stack install markov-chain' I attempted to get it to work with a stack.yaml file it refused to build.

--Usage-- 'stack Main.hs' or 'stack ghci', ':load Main', 'main'

--ANSI escape codes for coloring text and formatting https://en.wikipedia.org/wiki/ANSI_escape_code alternative I found too late https://hackage.haskell.org/package/ansi-terminal-0.6.2.3/docs/System-Console-ANSI.html

putStr \ESC[2J --clears the terminal

--Recursive IO section provides a very basic look at what IORef does. Hoogle gave no indication for its use. https://www.michaelburge.us/2017/08/15/how-do-i-modify-a-variable-in-haskell.html#state-monad
