Testing

Some basic unit tests using PHPUnit are in /tests, with sample files in /tests/fixtures (run generate.php from there first and on each pull), more coverage and any Github-friendly samples are always welcome. Some optional tests require external binaries (see /tests/bin/README.md). Enjoy :)
