Give users the bit of JS that delays the JS until load

[danjenkins]

I always start out with the generator and I always have to fill in the onload functions

I'm guessing this would be useful to other people too

Otherwise you just get "can't add listener to null"

What would you add exactly?

[danjenkins]

function ready(fn) {
  if (document.readyState != 'loading'){
    fn();
  } else {
    document.addEventListener('DOMContentLoaded', fn);
  }
}
