* Added copyright and license header
* Updated files on which it runs on
* SystemVerilog not to be supported, since now there are some pkg files
that do not have the format of a Verilog file, thus making the
checker to fail all the time -- which is not good
* Now it can run on files which contain JESD in their paths, because
now all of them have the copyright on the same line (but the
copyright inside the JESD license can't be checked yet by the script)
