ES5 + .extend is not necessary for this simple chunk.
(function($){
if (!Object.create)
var F = function(){};
$.beget = function (proto, props) {
if(Object.create)
var o = Object.create(proto);
else {
F.prototype = proto;
var o = new F;
}
for ( var k in props )
o[k] = props[k];
return o;
};
})(jQuery);
