title: Converting a CGPoint to NSValue
body: <p>In <code>CABasicAnimation.fromValue</code> I want to convert a <code>CGPoint</code> to a "class" so I used <code>NSValue</code> <code>valueWithPoint</code> but in device mode or simulator one is not working...
  need to use <code>NSMakePoint</code> or <code>CGPointMake</code> if in device or simulator.</p>
