      # A MongoDB map reduce operation.
      #
      # @note A map/reduce operation can behave like a read and
      #   return a result set, or can behave like a write operation and
      #   output results to a user-specified collection.
      #
      # @example Create the map/reduce operation.
      #   MapReduce.new({
      #     :selector => {
      #       :mapreduce => 'test_coll',
      #       :map => '',
      #       :reduce => ''
      #     },
      #     :db_name  => 'test_db'
      #   })
      #
      # Initialization:
      #   param [ Hash ] spec The specifications for the operation.
      #
      #   option spec :selector [ Hash ] The map reduce selector.
      #   option spec :db_name [ String ] The name of the database on which
      #     the operation should be executed.
      #   option spec :options [ Hash ] Options for the map reduce command.
      #
      # @since 2.0.0
