Override jquery.delegate() to accept an object

$.fn.delegate.js

/**
 * Override .delegate()
 * if 'selector' is an object loop over the object and call .live() for each item
 * otherwise it call .live() just like the original .delegate().
 * Roughly similar to the way the map is implemented in .bind().
 */
    $.fn.delegate = function(selector, types, data, fn) {
        if (typeof selector === "object") {
            for (var sel in selector) {
                for (var type in selector[sel]) {
                    this.live(type, data, selector[sel][type], sel);
                }
            }
            return this;
        } else {
            return this.live(types, data, fn, selector);
        }
    };

I assume .delegate now calls .on() underneath?
