    Do with it what you will.

    Usage:
    
    $(document).ready(function(){
        $('body').upUpDownDown({
            watchFor: [38,38,40,40,37,39,37,39,66,65], // Array of keyCode and charCodes to watch for
                                                       // This represents a sequence, ordered left (first) to right 
                                                       (last), so:
                                                       // [38,38,40,40,37,39,37,39,66,65] == up up down down left right 
                                                       left right B A, in that order
            callback: function(){
                // Do some fancy shit here.
            }
        });
    });
