Well, rebuilt my RUby Gem Werds in Elixir, and this time put some comments and tests in. In the process realised the code I wrote originally wasn't the best.

Still got some bureaucracy around putting it as a library, which I will do when creating juices are running low.

Next plan is a Phoenix app to put the library to use helping people with word puzzles.
