title: angular: updating scope on hover
body: <p>I'd like some child div of a main div be hidden by default an visible when you hover over the main div.</p>
  
  <p>I'm trying to have that native in angular and forget the <code>.hover()</code> way in jquery.</p>
  
  <p>I though about using <code>ng-show</code> on the child div and then updating the binding when I hover the main div. Is there a directive to listen for hovering?</p>
