title: How to animate Angular ui-grid when rows are added
body: <p>I have an Angular UI Grid element.  I am periodically adding new items at the front of the data array. I'm only adding a few at a time (like 1 to 5 new items)</p>
  
  <p>I would like the UI Grid to animate the new rows being added.  Right now the rows are added immediately, which makes it jumpy.  I want to the new rows to animate in so the UI Grid looks like it smoothly adds them in.</p>
  
  <p>Is this easily possible?  Is there an option for this?</p>
