      The $geoNear operator will be based on the geoNear command, supporting the same arguments with the same defaults as the command with the following exceptions:

      1) Arguments are nested as in {$geoNear: {near:[10,20], spherical:true}}
      2) limit is supported as a synonym for num (SERVER-5113).
      3) num/limit can also be set by a following $limit
      4) The matching documents are passed through the pipeline without a wrapper
      5) A new required argument "distanceField" specifies a field name to inject the distance into. This could be optional on non-sharded systems, but I think it is best to require it everywhere.
      6) includeLocs is still optional, but also takes a field to inject the location into.

      geoNear command is documented here http://docs.mongodb.org/manual/reference/command/geoNear/
