 *
 *  Thanks to M. Alsup http://www.malsup.com for his SWF plugin that was the basis for this code
 *
 *  This plugin converts anchor tags into iframes.
 *
 *
 *
 *  Sample HTML:
 *      before:  <a href="myIframe.html" class="iframe">My Iframe Link</a>
 * 
 *      after:   <div class=iframe>
 					<iframe id=content_iframe marginWidth=0 marginHeight=0 src="myIframe.html" frameBorder=0 width=640 height=480>
					</iframe>
				</div>
 *
 *  Usage:
 *      $('a.iframe').iframe();
 *
 *
 *
 *  Notes:
 *  -----
 *
 *  Options are passed to the 'flash' function using a single Object.  The options
 *  Object is a hash of key/value pairs.  The following option keys are supported:
 *
 *  Options:
 *  -------
 *  width:      	width of iframe (default: 640)			w:640
 *  height:      	height of iframe (default: 480)			h:480		
 *  scrolling:   	auto									sc:auto
 *  frameborder:	height of iframe (default: 0)			fb:0	
 *  marginwidth:	margin of iframe (default: 0)			wm:0		
 *  marginheight:	margin of iframe (default: 0)			hm:0	
 *
 *  * height, width, version and background values can be embedded in the classname using the following syntax:
 *    <a class="iframe w:450 h:450 scr:no"></a>
