title: AngularJs ReferenceError: angular is not defined
body: <p>I trying to add a custom filter, but if I use the following code:</p>
  
  <pre><code>angular.module('myApp',[]).filter('startFrom', function() {
      return function(input, start) {
          start = +start; //parse to int
          return input.slice(start);
      }
  });
  </code></pre>
  
  <p>But if I do so, I get: "ReferenceError: angular is not defined" in firebug.</p>
  
  <p>The rest of application is working fine, I am using ng-app in a tag div not in tag html, and <a href="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.3/angular.js">https://ajax.googleapis.com/ajax/libs/angularjs/1.0.3/angular.js</a></p>
