Configure check style in the project

[otaviojava]

Does make sense a PR with check style in the project?

This way, the project will easier to more person contribute and also to maintain the project, I believe that we could start with:

• number of characts in a line
• standard to Java class and method
• Make the header license mandatory
• Unused imports

@otaviojava thanks. This was one of the things that we had in our backlog queue, we haven't got into doing it yet.

It would help to have some validation on checkstyle integrated in the maven pom file.
Let's start with maven integration and not do any code change into the existing java breaking the codestyle validation for now.

Your PR for integrating this code style validation to maven pom file is welcomed. :-)

Ok, I'll open a PR soon

Closing old issues. (Still a good idea!)
