title: $.extend method with jquery bbq
body: <p>I define my routes object (jq bbq) and in some cases i have to add some new/additional to the already existing routes object with </p>
  
  <pre><code>$.extend(this.route, routeArray);
  </code></pre>
  
  <p>Is there a simple way to remove one route (or multiple routes) in the routearray? The order of the params varies.. Or is there a better way for doing this..?</p>
  
  <p>How could i compare my routeArray with an copy of the previous routearray (lastRoute) and check if only a param changed wich doesn`t require a new ajaxget? </p>
  
  <p>Exists there a easy possibility or have i to iterate over the routes object and check every param 
  in the route object?</p>
  
  <p>need me some advice . . </p>
