  /**
   * jQuery Equal Height and Width Plugin - v2.0, 07.24.2008
   *
   * 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.
   *
   * Modifications to Original
   *
   *  - Cache selectors for huge performance gain.
   *  - Remove dependency to pixel and em conversion.
   *  - Remove old IE shims.
   *
   * Jon LaBelle <jon@tech0.com>
   *
   * @example
   *   $(selector).equalHeights();
