title: What providers / services are available in module.config?
body: <p>I want to use $document to grab a server value from an input field.</p>
  
  <pre><code>var base_url = $document[0].getElementById('BaseUrl').value;
  </code></pre>
  
  <p>The base url is used for grabbing templates.</p>
  
  <pre><code>var base_url = $document[0].getElementById('BaseUrl').value;
  
  $routeProvider.when('/alert', {
    controller: function () { },
    templateUrl: base_url + '/partials/instances.html'
  });
  </code></pre>
  
  <p>Since $document throws an error that it's unknown I am guessing that it's not available at config? Is there a way to find out what is available and what not? I could also use $http to get data from the server but that's also not available.</p>
