Don't submit ES6 source to npm - compile first, and only publish ES5 code

[stevus]

Put this in your package.json which will auto-compile/transpile your code before publishing to NPM:

"scripts": {
    "compile": "babel -d lib/ src/",
    "prepublish": "npm run compile"
},

This way, I don't need to transpile your module to use it in my project. You would just publish as normal:

npm publish ./

I think I'm going to close this out. I only really want to support Node 4.x going forward, since that has ES6 support.
