 * javascript method: "pxToEm"

 * Copyright (c) 2008 Filament Group

 *
 * 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
