Copyright Messages Cleanup

Tox and pep8 failed due to multiple reason causing
our verify-python jobs to fail. One reason being the
failure of test cases. Added sample test case for
developers to follow. Another reason was the Copyright
message appearing in supposedly empty package files.
Removed copyright messages so pep8 can succeed.
