Parsing JSON in Scala: Use Argonaut

I followed these answers on Stack Overflow to find an easy way to parse JSON with Scala, but it wasn't easy.

The only thing that ended up working for me was Argonaut.

I just couldn't get the play-json and lift-json to work with sbt and intellj. The play framework seems to have its own sbt-plugin and I didn't want to add that just to get its JSON functionality.

I added my own answer to the Stack Overflow question to describe my basic setup. Includes codes.
