title: How to set Incremented value in nodes of neo4j
body: <p>I have a couple of nodes and I need to add a incremental value in all nodes of a particular label.</p>
  
  <pre><code>match wd= (w:MYNODE)
   forEach(n IN nodes(wd)|
    set n.incrementalId=??
  );
  </code></pre>
  
  <p>currently I have tried for each to traverse on each node but unable to get index of the each loop
  ps: I have also tried with but unable to increment ie ++ the current value.</p>
