 #### lookup(request, response, [context], [done])

 Start a new search, `request` and `response` are the server req/res objects.<br>
 If a route is found it will automatically call the handler, otherwise the default route will be called.<br>
 The url is sanitized internally, all the parameters and wildcards are decoded automatically.
