Comment(by edward.scheinerman):
This new graphs.IntervalGraph and the repaired graphs.RandomInterval work
as advertised. Nicely done Nathann.
However, I think graphs.Interval should allow repeated intervals, e.g.,
g = graphs.IntervalGraph( [(0,2), (0,2), (1,5), (3,7)] )
should create a graph with four vertices (not three as the method
currently does).
