Stack Warnings and Extra-Deps #26

To use functionality in Control.Monad.Except, need version 2.2.2 of mtl module, which is not yet in stack snapshot.
Have added it to extra-deps in stack.yaml which causes warnings when compiling:

"No packages found in snapshot which provide a "happy" executable, which is a build-tool dependency of "VHDL-Sim"
Missing build-tools may be caused by dependencies of the build-tool being overridden by extra-deps.
This should be fixed soon - see this issue commercialhaskell/stack#595

Should monitor this and perhaps remove mtl-2.2.2 from extra-deps once it has been added to stack resolver.
