Try porting to Phoenix

[marnen]

I think this might be a good application for me to learn Phoenix, especially now that I have some functionality already implemented in Rails. I tried this once before, at http://www.github.com/marnen/contraq-elixir, but at that time, I didn't have the functionality implemented, and it turned out that learning a new environment and simultaneously implementing an application was too much to do at once.

Phoenix has changed a good deal since my last attempt, so I think I'm going to start the port pretty much from scratch, though I'll use code from the older attempt as necessary.

• [x] Get dev environment working
• [x] Create a Phoenix application
• [x] Get testing tools installed (white-bread and ESpec)
• [x] Set up mix test.watch
• [ ] Reimplement functionality such that existing Gherkin features pass
• [ ] Fix up HTML to match what we already have
• [ ] Get Erlang observer/debugger working from within container (see https://github.com/c0b/docker-erlang-otp/issues/41)
• [x] Try Dialyzer/Dialyxir/Dialyzex
• [ ] Set up Distillery or something for packaging
• [ ] Set up Travis
• [ ] Make sure anything else that needs tweaking gets tweaked :)

I thought we'd need ex_machina for factories, but we may just be able to use Ecto.

https://github.com/batate/blacksmith also looks interesting for factories.
