title: How to add a contact without a name in GAS?
body: <p>I have a collection of contact info that I would like to add to Google Contacts via the ContactsApp. Is some cases this info is just an e-mail address without a name.</p>
  
  <pre><code>contact = ContactsApp.createContact("tmp1", "tmp2", "email");
  </code></pre>
  
  <p>The above doesn't seem to accept "" as an argument. Neither do the following:</p>
  
  <pre><code>contact.setGivenName(".");
  contact.setFamilyName(":");
  contact.setFullName("*");
  </code></pre>
  
  <p>I could use " ", but that is not ideal. Is there any way to have the names be "" just like when an e-mail address is saved from a gmail message sent without the name being available?</p>
