 * Drupal.attachBehaviors is added below to the jQuery ready event and so
 * runs on initial page load. Developers implementing AHAH/AJAX in their
 * solutions should also call this function after new page content has been
 * loaded, feeding in an element to be processed, in order to attach all
 * behaviors to the new content.
 *
 * Behaviors should use a class in the form behaviorName-processed to ensure
 * the behavior is attached only once to a given element. (Doing so enables
 * the reprocessing of given elements, which may be needed on occasion despite
 * the ability to limit behavior attachment to a particular element.)
