title: Make React Native Modal appear from top to bottom
body: <p>I noticed that the <a href="http://facebook.github.io/react-native/docs/modal.html#animationtype" rel="nofollow noreferrer">Modal</a> component's <code>animationType</code> property only allows for it to slide from bottom to top. How could I change the animation and make the modal appear from top to bottom?</p>
  
  <p>Thanks for your time.</p>
