I refactored this project to use eslint and es6 complexity-parsing capability. It is working well. Someone suggested I should make a pull request here, but I wanted to ask if you were even interested in having me actively maintain this project. If not I don't mind keeping it in my es6-plato project.

I also updated all the npm dependencies (migrated lodash, etc)

Let me know!
