title: Cycle through array angular 2
body: <p>I have an array, and I want to display only one object in the array at a time. once I have one object showing I then want to cycle through that array via a button. I am able to get the array to display but I cant figure out how to just display one object at a time. Here is <a href="https://plnkr.co/edit/GBV27r6zjE391cYtfttz?p=preview" rel="nofollow noreferrer">plunker</a> of what I have so far.</p>
  
  <p>I am not exactly sure if I am using <code>*ngFor</code> correctly in this case. Thanks for any help!</p>
