urchin_notprovided.js

/*! handling of secure google search keyword being hidden and set as (not provided) for Google Analytics sites using urchin.js , not ga.js
 * see also : http://googleblog.blogspot.com/2011/10/making-search-more-secure.html
 * Google handles it only in ga.js, we provide it for sites using urchin.js
 * author : analytics(at)resoneo(dot)com 2011
 * https://gist.github.com/1373049
 * usage : include urchin.js ABOVE this code, set your parameters and call urchinTracker BELOW this code */
