Haskell + Travis CI

I have gotten Travis CI to build my Haskell doodles.

There was a little bit of cabal learning to get it going. It does not do much other than build-on-push, but that is a start.

Next will be to learn some testing frameworks for Haskell and get that going as part of the build.
