  // @todo: As far as I can tell this hook has zero impact. All the real saving
  // happens on hook_node_insert, which is triggered after this. Once a node is
  // created then hook_node_load ensures that the needed array is present on the
  // future editing of a node.

      // contains an associative array of tid to weight.
