title: Sending json array via Alamofire
body: <p>I wonder if it's possible to directly send an array (not wrapped in a dictionary) in a POST request. Apparently the <code>parameters</code> parameter should get a map of: [String: AnyObject]?
  But I want to be able to send the following example json:</p>
  
  <pre><code>[
      "06786984572365",
      "06644857247565",
      "06649998782227"
  ]
  </code></pre>
