/*
 * breadcrumb.js
 * 
 * njohnson@echoalley.com
 * adapted from source on WWW
 *
 * This file builds a breadcrumb trail based on the URL of
 * a page. It parses the string and takes everything between
 * the slashes (/) and assumes that the directory structure
 * mirrors the content structure. For instance,
 * 
 * http://www.echoalley.com/about_us/employee_profiles.php
 * 
 * becomes
 *
 * Home > About Us > Employee Profiles
 *
 * The last member of the breadcrumb trail is never a link because
 * it indicates the current page.
 *
