 * Copyright (c) 2008 Filament Group
 * Dual licensed under the MIT (filamentgroup.com/examples/mit-license.txt) and GPL (filamentgroup.com/examples/gpl-license.txt) licenses.
 *
 * 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

		For example, if the body font-size is 62.5% and the window width is 1000px, IE will return 625px as the font-size. 	
		When this happens, we calculate the correct body font-size (%) and multiply it by 16 (the standard browser font size) 
		to get an accurate em value. */

 * Description: Compares the heights or widths of the top-level children of a provided element 
 		and sets their min-height to the tallest height (or width to widest width). Sets in em units 
 		by default if pxToEm() method is available.
 * Dependencies: jQuery library, pxToEm method	(article: 
		http://www.filamentgroup.com/lab/retaining_scalable_interfaces_with_pixel_to_em_conversion/)
 * Usage Example: $(element).equalHeights();
  		Optional: to set min-height in px, pass a true argument: $(element).equalHeights(true);
 * Version: 2.0, 08.01.2008
