Support for factor graphs

[tdiethe]

How hard would it be to create factor graphs, for example in the style of tikz bayesnet? I'm a big fan of these, since it makes more of the model explicit in the graph.

I'm not sure what the question is, other than to answer "not that hard"?

The factors would just be nodes with shape="rectangle" if that answers the question.
