def add_edges(self, edgelist):
self.add_hyperedges(edgelist)<EOL>
Add given hyperedges to the hypergraph.

@attention: While hyperedge-nodes can be of any type, it's strongly recommended to use only
numbers and single-line strings as node identifiers if you intend to use write().

@type  edgelist: list
@param edgelist: List of hyperedge-nodes to be added to the graph.
