 * JQuery Plugin: "EqualHeights" & "EqualWidths"
 * by:  Scott Jehl, Todd Parker, Maggie Costello Wachs (http://www.filamentgroup.com)
 *

 * Licensed under GPL (http://www.opensource.org/licenses/gpl-license.php)
 *
 * 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, 07.24.2008
 * Changelog:
 *  08.02.2007 initial Version 1.0
 *  07.24.2008 v 2.0 - added support for widths

 * 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
