Not Autoloading and Missing License

[douglasgreen]

Thanks for providing this project. I noticed two small issues that I wanted to bring to your attention:

1. The composer.json file says that this project uses the MIT license, but there is no copy of the license included as a LICENSE file in the project itself.
2. The parser did not autoload for me. I think it is because the file is named parser.php but the class is named Parser with a capital P. I still got it to work by requiring the file with the require_once statement, though.
