docs: Get an L{iaxiom.IQuery} whose results will be values of a single
          attribute rather than an Item.
  
          @param attributeName: a L{str}, the name of a Python attribute, that
          describes a column on the Item subclass that this query was specified
          for.
  
          @return: an L{AttributeQuery} for the column described by the attribute
          named L{attributeName} on the item class that this query's results will
          be instances of.
