/**
 * PF_collapsible.js
 *
 * Allows for collapsible fieldsets.
 *
 * This code was originally based heavily on the 'coolfieldset' jQuery plugin:
 * http://w3shaman.com/article/jquery-plugin-collapsible-fieldset
 *
 * Now it's less so, because that code used a .toggle() function that was
 * removed in jQuery 1.9.
