/* YOU SHOULD DELETE THIS CHANGELOG TO REDUCE FILE SIZE:
 * v1.2.1 altered:  2nd July 07. added hide() before animate to make work for jQuery 1.1.3. See comment in 'over' function.
 * v1.2.2 altered:  2nd August 07. changed over function .find('ul') to .find('>ul') for smoother animations
 * 				    Also deleted the iframe removal lines - not necessary it turns out
 * v1.2.3 altered:  jquery 1.1.3.1 broke keyboard access - had to change quite a few things and set display:none on the
 *				    .superfish rule in CSS instead of top:-999em
 * v1.3	: 		    Pretty much a complete overhaul to make all original features work in 1.1.3.1 and above.
 *				    .superfish rule reverted back to top:-999em (which is better).
 * v1.3.1 altered:  'li[ul]' to $('li:has(ul)') to work with jQuery 1.2
 * v1.3.2: 			added onshow callback option as requested - 'this' keyword refers to revealed ul.
		   			fixed bug whereby multiple menus on a page shared options. Now each menu can have separate options.
					fixed IE6 and IE7 bug whereby under certain circumstances => 3rd tier menus appear instantly with text missing when revisited
 * v1.3.3: 			altered event attachment selectors for performance increase on menu setup.

	/**
	 * The bgiframe is chainable and applies the iframe hack to get 
	 * around zIndex issues in IE6. It will only apply itself in IE6 
	 * and adds a class to the iframe called 'bgiframe'. The iframe
	 * is appeneded as the first child of the matched element(s) 
	 * with a tabIndex and zIndex of -1.
	 * 
	 * By default the plugin will take borders, sized with pixel units,
	 * into account. If a different unit is used for the border's width,
	 * then you will need to use the top and left settings as explained below.
	 *
	 * NOTICE: This plugin has been reported to cause perfromance problems
	 * when used on elements that change properties (like width, height and
	 * opacity) a lot in IE6. Most of these problems have been caused by 
	 * the expressions used to calculate the elements width, height and 
	 * borders. Some have reported it is due to the opacity filter. All 
	 * these settings can be changed if needed as explained below.
	 *
	 * @example $('div').bgiframe();
	 * @before <div><p>Paragraph</p></div>
	 * @result <div><iframe class="bgiframe".../><p>Paragraph</p></div>
	 *
	 * @param Map settings Optional settings to configure the iframe.
	 * @option String|Number top The iframe must be offset to the top
	 * 		by the width of the top border. This should be a negative 
	 *      number representing the border-top-width. If a number is 
	 * 		is used here, pixels will be assumed. Otherwise, be sure
	 *		to specify a unit. An expression could also be used. 
	 * 		By default the value is "auto" which will use an expression 
	 * 		to get the border-top-width if it is in pixels.
	 * @option String|Number left The iframe must be offset to the left
	 * 		by the width of the left border. This should be a negative 
	 *      number representing the border-left-width. If a number is 
	 * 		is used here, pixels will be assumed. Otherwise, be sure
	 *		to specify a unit. An expression could also be used. 
	 * 		By default the value is "auto" which will use an expression 
	 * 		to get the border-left-width if it is in pixels.
	 * @option String|Number width This is the width of the iframe. If
	 *		a number is used here, pixels will be assume. Otherwise, be sure
	 * 		to specify a unit. An experssion could also be used.
	 *		By default the value is "auto" which will use an experssion
	 * 		to get the offsetWidth.
	 * @option String|Number height This is the height of the iframe. If
	 *		a number is used here, pixels will be assume. Otherwise, be sure
	 * 		to specify a unit. An experssion could also be used.
	 *		By default the value is "auto" which will use an experssion
	 * 		to get the offsetHeight.
	 * @option Boolean opacity This is a boolean representing whether or not
	 * 		to use opacity. If set to true, the opacity of 0 is applied. If
	 *		set to false, the opacity filter is not applied. Default: true.
	 * @option String src This setting is provided so that one could change 
	 *		the src of the iframe to whatever they need.
	 *		Default: "javascript:false;"
