title: dgrid pagination example
body: <p>Can anyone point me to an example of using the Pagination extension of dgrid with a dgrid? This could be a reference link or a simple example you type up. I've defined it in my code, used it with an OnDemandGrid where it is added to the declare mixin for my custom grid. I see arrows for page navigation, I see the page size setting menu, but my specification of rowsPerPage: 3 does nothing. I still see my 7 sample records.</p>
  
  <p>I'm using a modified Cache (data object store) that wraps a JsonRest and Memory store for my dgrid.</p>
