+/**
+ * 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
+ * @type jQuery
+ * @cat Plugins/bgiframe
