jQuery-based window resizing hook with rate limiting

smootherWindowResize.js

/*

Usage: $.windowResize(yourFunction);

Intended as a replacement for $(window).resize(yourFunction)
yourFunction will only be called once the resize action has been completed, improving performance

Code is public domain
