file for Sudoku module (can be run with runhaskell). modified cabal
file to build scotty service. working on addin web service.
included scotty in cabal file
scotty service has basic outline in. it will respond to root requests
with instructions. it will respond to blank solve request with
instructions. it will no yet solve or generate anything. it just has
placeholders for now. it also has no error handling yet.
