/**
* DD_roundies, this adds rounded-corner CSS in standard browsers and VML sublayers in IE that accomplish a similar appearance when comparing said browsers.
* Author: Drew Diller
* Email: drew.diller@gmail.com
* URL: http://www.dillerdesign.com/experiment/DD_roundies/
* Version: 0.0.2a
* Licensed under the MIT License: http://dillerdesign.com/experiment/DD_roundies/#license
*
* Usage:
* DD_roundies.addRule('#doc .container', '10px 5px'); // selector and multiple radii
* DD_roundies.addRule('.box', 5, true); // selector, radius, and optional addition of border-radius code for standard browsers.
*
* Just want the PNG fixing effect for IE6, and don't want to also use the DD_belatedPNG library? Don't give any additional arguments after the CSS selector.
* DD_roundies.addRule('.your .example img');
