 """Adds multiple hyperedges to the graph, along with any related attributes of the hyperedges. If any node in the tail or head of any hyperedge has not previously been added to the hypergraph, it will automatically be added here. Hyperedges without a "weight" attribute specified will be assigned the default value of 1. :param hyperedges: iterable container to either tuples of (tail reference, head reference) OR tuples of (tail reference, head reference, attribute dictionary); if an attribute dictionary is provided in the tuple, its values will override both attr_dict's and attr's values. :param attr_dict: dictionary of attributes shared by all the hyperedges. :param attr: keyword arguments of attributes of the hyperedges; attr's values will override attr_dict's values if both are provided. :returns: list -- the IDs of the hyperedges added in the order specified by the hyperedges container's iterator. See also: add_hyperedge Examples: :: (("A", "C"), ("B"), {'weight': 2}), (set(["D"]), set(["A", "C"]))) """
