      Description

      The cursor field for an explain() may look like this:

      { "cursor" : "BtreeCursor x_1 reverse multi" }

      Rather than storing all of this information in the same field, we could break it up in to separate fields:

      { "cursor" : "BtreeCursor",
      "index":

      {x: 1}

      ,
      "iterators": ["reverse", "multi"]
      }

      Not sure on the name of the last one, but you get the idea.
