/**
* jQuery.fn.dualSlider - Dual sliders, why not?
* Date: June 2010
*
* @author Rob Phillips http://www.robertjamesphillips.com (Front End Developer - Hugo & Cat - http://www.hugoandcat.com)
* @version 0.3
* @web http://www.hugoandcat.com/DualSlider/index.html
*
* Requirements:
* jquery.1.3.2.js - http://jquery.com/
* jquery.easing.1.3.js - http://gsgd.co.uk/sandbox/jquery/easing/
* jquery.timers-1.2.js - http://plugins.jquery.com/project/timers
*
* 0.2 - Tested and fixed for IE6+, auto loops, manual pause/play controls
*     - Disabled buttons until animation finishes - Thanks for the bug John.
* 0.3 - Now with a seamless loop, instead of that nasty rewind...was 'too much' apparently
