 * Description: Compares the heights of the first-children of a provided element 
 								  and sets their min-height to the tallest height. Sets in em units by default if pxToEm() method is available.
 * Dependencies: jQuery library, pxToEm method								  
 * Usage Example: $(element).equalHeights();
   						      Optional: to set min-height in px, pass a true argument: $(element).equalHeights(true);
 * Version: 1.0, 08.02.2007
 * Changelog:
 *  08.02.2007 initial Version 1.0
