Quick each (took from here without spaces)

// The `quickEach` method will pass a non-unique jQuery instance
// to the callback meaning that there will be no need to instantiate
// a fresh jQuery instance on each iteration. Most of the slow-down
// inherent in jQuery's native iterator method (`each`) is the constant
// need to have access to jQuery's methods, and so most developers
// see constructing multiple instances as no issue... E.g.
// $(...).each(function(){ $(this)... $(this)... $(this)... });
// A better approach would be `quickEach`.
