/**
 * 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;"
