 * Script used to level heights across multiple divs
 * Requires: jquery.js
 * Usage: a. Add script tags for this and jquery.js to page
 *        b. Add calls to normalizeHeights() for each group
 *           of divs you wish to balance to the 
 *           setAllHeights() function below.
 *        c. It seems safest to order the calls to 
 *           normalizeHeights() from innermost to outermost
