+/**
+ * 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;"
+ *
+ * @name bgiframe
+ * @type jQuery
