Description:
 def paginate_dict(function_ref, *argv, **kwargs):
 """ Paginate through a query that returns a dict result, and return the combined result. Note that this function requires some special kwargs to be passed in: * __alc_marker_path__ - The dictionary path to the Marker for the next result set. If this path does not exist, the raw result will be returned. * __alc_data_path__ - The dictionary path to the list containing the query results. This will be updated with the results of subsequent queries. * __alc_marker_param__ - The parameter name to pass to ``function_ref`` with the marker value. These paths should be lists, in a form usable by :py:func:`~._get_dict_value_by_path`. :param function_ref: the function to call :type function_ref: ``function`` :param argv: the parameters to pass to the function :type argv: tuple :param kwargs: keyword arguments to pass to the function :type kwargs: dict """
