title: ReferenceError: _ is not defined while using angular-google-maps
body: <p>I'm getting <code>ReferenceError: _ is not defined</code> the <a href="http://angular-ui.github.io/angular-google-maps/#!/" rel="noreferrer">angular-google-maps</a></p>
  
  <p>I don't really understand why I'm getting this error, because I'm doing exactly what it is written on the website.</p>
  
  <p>Also I searched for similar questions, but they didn't helped.</p>
  
  <p><strong>bundle.js</strong></p>
  
  <pre><code>$ = window.$ = window.jQuery = require('./lib/jquery');
  require('./lib/angular-simple-logger.js');
  require('./lib/angular-google-maps.js');
  require('./lib/lodash.js');
  </code></pre>
  
  <p>I'm importind <code>bundle.js</code> into the <code>index.html</code>. I also tried to use <code>ngLodash</code>, but no results.</p>
  
  <p><strong>app.js</strong></p>
  
  <pre><code>var app = angular.module('app', [
    'ngLodash',
    'nemLogging',
    'uiGmapgoogle-maps'
  ]);
  
  app.config(function(uiGmapGoogleMapApiProvider) {
      uiGmapGoogleMapApiProvider.configure({
         key: '{myKey}',
         v: '3.20',
         libraries: 'places' // I don't need the whole map, only the places
     });
  });
  </code></pre>
  
  <p>Also I enabled the <code>GoogleMaps Api</code> from the <code>Google Developer Console</code></p>
  
  <p>Does someone have some experience with this library and can give me a hint?</p>
