/**
 * The bgiframe is chainable and applies the iframe hack to get 
 * around zIndex issues in IE6. It will only apply itself in IE 
 * and adds a class to the iframe called 'bgiframe'.
 * 
 * It does take borders into consideration but all values
 * need to be in pixels and the element needs to have
 * position relative or absolute.
 *
 * NOTICE: This plugin uses CSS expersions in order to work
 * with an element's borders, height and with and can result in poor 
 * performance when used on an element that changes properties 
 * like size and position a lot. Two of these expressions can be
 * removed if border doesn't matter and performance does.
 * See lines 39 and 40 below and set top: 0 and left: 0
 * instead of their current values.
 *
 * @example $('div').bgiframe();
 * @before <div><p>Paragraph</p></div>
 * @result <div><iframe class="bgiframe".../><p>Paragraph</p></div>
 *
 * @name bgiframe
