Source code layout

[luizvarela]

One thing that I noticed is the four spaces in the generated models, following the Elixir style guide, two spaces are preferred. Also, the lib code is using 4 spaces too.
I think we can start changing the Ecto models first and then the entire source code. What do you think?

Good idea. It should be an easy fix for the models as there is a helper function that formats. Feel free to make the change if you want
