make 2 example apps using mtl and effects that asks password:

• State - number of wrong passwords
• Reader - right password from file
• MonadLog - just log, enterleaving monad (should I implement liftLog? https://www.youtube.com/watch?v=8t8fjkISjus, https://hackage.haskell.org/package/transformers-base-0.4.4/docs/Control-Monad-Base.html)
• MonadThrow - throw on wrong
• MonadIO or MonadMock - tests

MonadLog should be done 2 ways:

1. ReaderT - log to file (IO)
2. StateT - log to string
