[sten0]

By examining the git history I found that Glauber Alex Dias Prado and Thomas Frössmam both committed more than 15 lines of changes to this file in 2012. If they didn't attribute copyright to you, please add a copyright header with their information. If they did attribute it to you, please make this explicit by adding yourself to the file's copyright header. It's ambiguous right now.
