title: firebase is not defined in Angular app (after Firebase migration)
body: <p>Hi I'm trying to retrieve information from my database on Firebase in angular. However, I get an error <code>'firebase is not defined'</code></p>
  
  <pre><code>var config = {
      databaseURL: 'https://console.firebase.google.com/project/face-find-31e52/database/data/',
  };
      firebase.initializeApp(config);                           
      firebase.database().ref    
      ('/project/app-name/database/data').once('value').then(function(snapshot) {                                        
            $scope.data = snapshot.val();
      });
  </code></pre>
  
  <p>*note I don't have the user id in my url right now for authentication becauase I'm testing the app (solve one problem at a time right?)</p>
  
  <p>I included the firebase library in my html before I linked my app.js</p>
  
  <pre><code> &lt;script src="https://www.gstatic.com/firebasejs/3.0.0/firebase.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>I also remembered to include this in my angular:</p>
  
  <pre><code>angular.module('starter', ['ionic', 'ngCordova','firebase'])
  
  .controller("ExampleController", function ($scope, $cordovaCamera,$cordovaToast,$firebaseObject) {
  </code></pre>
  
  <p>Yes I"m building an ionic app, but I don't believe that this has any interference with firebase.Does anyone know why I can't retrieve the data? Help would be greatly appreciated. Thanks</p>
