CollectionNode fetches all content from NSFetchResultsController

[zboralski]

This is the first time I am not using the batch fetching api in a collection node or table node. I can't figure out how to prevent all the cells from being loaded right away. I tried to implement constrainedSizeForItem as I supposed that the cellnodes are being accessed to compute their size:

extension ContactsCollectionNode: ASCollectionDelegate {
  func collectionNode(_ collectionNode: ASCollectionNode, constrainedSizeForItemAt indexPath: IndexPath) -> ASSizeRange {
          let width = collectionNode.view.frame.width
          return ASSizeRange(min: CGSize(width: width, height: width),
                             max: CGSize(width: width, height: width))  }
}

Using a TableViewController.... my cells are loaded only as I scroll down.
