Package contains ES6 syntax

[DaveVdE]

We're having some trouble using this package because our pipeline currently does not transpile external modules into the ES5 that the browser loves. This is intentional. Package maintainers should still target ES5, or am I wrong?

Anyway, we've forked the repo to replace the use of arrow functions until this is solved.

yea I should have included this from the start - I've added a dist folder that has compiled to es5 files

#14. npm version 3.3.1 includes this.

should be all set, let me know if you run into any issues.
