title: Get Nib name/What exactly is a nib?
body: <p>I'm trying to implement a page menu segue in my app using the pod from 
  <a href="https://github.com/uacaps/PageMenu" rel="noreferrer">this pre-built page menu pod from github</a></p>
  
  <p>In the instructions, it says:</p>
  
  <pre><code>    var controller : UIViewController = UIViewController(nibName:"controllerNibName", bundle: nil)
      controller.title = "SAMPLE TITLE"
      controllerArray.append(controller)
  </code></pre>
  
  <p>This is my code:</p>
  
  <pre><code>    var chatAreaCtrl : UIViewController = ChatAreaCtrl(nibName: "ChatAreaCtrl", bundle: nil)
      chatAreaCtrl.title = "Chats"
      controllerArray.append(chatAreaCtrl)
  </code></pre>
  
  <p>Which gets me the error:</p>
  
  <pre><code>    Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: ...(loaded)' with name 'ChatAreaCtrl''
  </code></pre>
  
  <p>I'm pretty new to programming and Swift but I guess I'm not specifying the what the Nib is correctly?</p>
  
  <p>Thanks!</p>
