9e7571fb98This commit will make sure that every class, interface, or trait will have the "@author" annotation in it. In order to create a list of authors, I used the "git blame" command, which means that if someone changed or even created the file but does not have any remaining line will not be shown in the list; it's a trade-off worth but it is worth it. The other way to do it would be carefully checking each file. Signed-off-by: Henrique Moody <henriquemoody@gmail.com>
