+ *
+ * Description: Extends the native Number and String objects with pxToEm method. pxToEm converts a pixel value to ems depending on inherited font size.  
+ * Article: http://www.filamentgroup.com/lab/retaining_scalable_interfaces_with_pixel_to_em_conversion/
+ * Demo: http://www.filamentgroup.com/examples/pxToEm/	 	
+ *							
+ * Options:  	 								
+ 		scope: string or jQuery selector for font-size scoping
+ 		reverse: Boolean, true reverses the conversion to em-px
+ * Dependencies: jQuery library						  
+ * Usage Example: myPixelValue.pxToEm(); or myPixelValue.pxToEm({'scope':'#navigation', reverse: true});
+ *
+ * Version: 2.0, 08.01.2008 
+ * Changelog:
+ *		08.02.2007 initial Version 1.0
+ *		08.01.2008 - fixed font-size calculation for IE
