Some classes and one trait had some mismatch values for their "@author" annotation and this commit will fix the mismatch putting the correct authors. I used the "git blame" command to find out which people changed the file and created a list based on that information. Signed-off-by: Henrique Moody <henriquemoody@gmail.com>
