title: Google Places Autocomplete API filter by multiple countries
body: <p>Looking for a way to filter the autocomplete results filtered by 2 countries, Canada and US.</p>
  
  <p>Currently I can only filter by one or the other with options like this...</p>
  
  <pre><code>var options = {
    types: ['(cities)'],
    componentRestrictions: {country: 'us'}
  }
  var autocomplete = new google.maps.places.Autocomplete(input,options);
  </code></pre>
  
  <p>... but I have not seen any documentation that explains how to restrict autocomplete results to 2 countries.</p>
  
  <p>Any help is appreciated.</p>
