Using Markdown With Recipient Variable with Batch Sending

[dukesnuz]

My objective is to use batch sending with recipient variables and mardown.
Should this code work?

I am currently getting the following error I posted in Issue #120

  Mailgun::send($view, $data, function($message) use($recipients){
    $message->to($recipients);
    $message->recipientVariables($recipients);
    $message->subject('Available Loads:');
  });```


Thank you for any help that may be provided.
