/**
 *
 * KDS Navify! v0.3 
 * Last rev. 2011-07-01
 *
 * Purpose:
 * The script will find all links in the nav, and apply the "active" class to both the link ("A") and its closest parent list item ("LI").
 * You can then use these hooks for some nice CSS styling or whatever.
 *
 * Sample usage:
 * $('ul#navigation').navify();
 *
 * Or for multiple navs:
 * $('#main-nav, #side-nav, ul.nav-list').navify();
 *
 * Optionally you can pass in your own className to use instead if you don't like the default, e.g.,
 * $('ul.nav').navify('myOwnActiveClassName');
 *
