"""Define :class:`Graph`, a directed, acyclic graph structure.

We can list all of a node's ancestors.

Ancestors works with cycles.
>>> a.append(d)
- >>> print [node for node in d.ancestors()]

[b, c, a, d]
We can find the cycle path.
- >>> print d.parent_path(d)

[b, a, d]
After a run through :meth:`Graph.set_children`, we can also
>>> g = Graph([a, b, c, d])
>>> g.set_children()
- >>> print a.children
+ >>> print(a.children)
[b, c]
And descendents.
