title: Creating stripe token using separate elements
body: <p>Instead of using the element type 'card' I needed to separate the elements, In the documentation example they only use 'card' so when they create a token they just pass the card object to the create token parameter.</p>
  
  <pre><code>stripe.createToken(card).then(function(result) {
  
  });
  </code></pre>
  
  <p>How can I pass these multiple objects to create a token?</p>
  
  <pre><code>var cardNumber = elements.create('cardNumber');
  cardNumber.mount('#card-number');
  var cardExpiry = elements.create('cardExpiry');
  cardExpiry.mount('#card-expiry');
  var cardCvc = elements.create('cardCvc');
  cardCvc.mount('#card-cvc');
  var cardPostalCode = elements.create('postalCode');
  cardPostalCode.mount('#card-postal-code');
  </code></pre>
