	 *
	 * 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
