Contributor guidelines

Please contribute and update the todo list with your ideas

As a Pacto contributor
I want to contribute following some guidelines
So I can participate more effectively in the project

It was previously discussed that we need some guidelines for contributors so everybody proposes ways to contribute and agrees. We have to take more actions about this like on #28 that was a starting point to have a more consistent codebase,

These is a initial list of things to be addressed:

• Create a page on the project that explains the best way to contribute on the project
• Have a guideline on the best way for us to write specs
• Have a guideline on the best way for us to write production code

We could adopt the guideline for testing http://betterspecs.org/. Also the PR #37 is following part of that guideline and is trying to bring more consistency to the specs.

Great guide! We need to follow this steps on a clean environment to see if we really don't need anything else, but it looks good.
