def add_edge(self, hyperedge):
self.add_hyperedge(hyperedge)<EOL>
Add given hyperedge 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  hyperedge: hyperedge
@param hyperedge: Hyperedge identifier.
