It looks like this PR contains more than just adding the .editorconfig?

Was the POMs being reformatted a result from opening it in your IDE, then please turn off automatic reformatting ;) If it is the result from applying the .editorconfig can you do it in 2 PRs?

Can you also open an issue that corresponds to the PR? This will make it easier for folks to see the changes as everything is then just tracked using issues.

Thanks!

Here is the issue : #139

I've added the .editorconfig and made sure it didn't change any existing formatting rules. While scrolling around, I noticed there was some inconsistency in the formatting of the pom.xml headers (some pom.xml had the header in just one line, others split into several lines). So I manually changed the formatting
