  === Expire node(s) at specified time
  
  The `apoc.ttl.expire` procedure deletes a node or group of nodes after the datetime specified.
  
  To remove a single node or set of nodes, we can use a selection query prior to calling the procedure that defines which nodes we want to apply the time-to-live label and property.
  We then call the procedure and pass in the selected node(s), the future datetime at which we want the nodes to be removed, and the specificity of the datetime (seconds, milliseconds, etc).
