title: Implementing a reverse infinite scroll using ngInfiniteScroll directive in AngularJS
body: <p>I would like to use the <code>ngInfiniteScroll</code> directive from here: <a href="http://binarymuse.github.io/ngInfiniteScroll/">http://binarymuse.github.io/ngInfiniteScroll/</a> in my angular js app to implement a reverse infinite scroll (like in a chat widget). However the documentation for this directive does not seem to mention how this can be accomplished. It only documents how the standard infinite scroll is implemented. Could someone guide me in this regards? Thanks! </p>
  
  <p>P.S : I'm keen on using this directive since it deals with the DOM control; the standard infinite scroll directive from angular keeps creating DOM elements as I scroll which is never deleted. </p>
