Yep, that is the aim. Plus it is already the current 'default' chosen
by Graph(). On the other hand, the future behaviour of
Graph([(0,1),(0,1),(0,1),(0,1)]) will be a graph with two points and
one edge between them.
This is more or less what happens when you do:
g = Graph()
g.add_edges([(0,1),(0,1),(0,1),(0,1)])
For one year the Graph([(0,1),(0,1),(0,1),(0,1)]) will raise a warning
("You should set multiedges=True"), and at the end of that "all graphs
will be simple, unless explicitly specified otherwise".
