A GraphQL parser written in PHP. The parser is able to parse the full [spec](https://facebook.github.io/graphql/). This package is compatible with PHP 5.3+. I'm still actively working on this project. Expect things to break. 🙈

This package is being developed together with a server package, which isn't public yet.
