title: connect nodes with NEXT replation by date
body: <p>i have this sample graph:</p>
  
  <p><a href="http://console.neo4j.org/?id=mginka" rel="nofollow">http://console.neo4j.org/?id=mginka</a></p>
  
  <p>and i'm trying to find a Cypher code,that will connect all the hits nodes of each session by the date_time field with [NEXT] relation –
  hits from different sessions shouldn't be connected..</p>
  
  <p>thanks,
  Lior</p>
