 * 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
