A cross-browser way of handling the document onReady event.
Provides a way to set a function that will run after DOM is ready.
A common way to use:
ready(function() {
// we are ready
console.log('ready!');
});
ready returns itself, so you can add another function right away:
ready(function(){
console.log('ready 1');
})(function() {
console.log('ready 2');
});
