Kruschke diagrams as an option in model_to_graphviz or with a separate model_to_kruschke

[opherdonchin]

Kruschke plots, as used in Doing Bayesian Data Analysis, and as described in this blog post are preferred by many users to the style of diagramming produced by model_to_graphviz. I've looked a bit at the code, and I don't think it should be hard to modify it to create Kruschke diagrams.

I'm scared to start on my own. I'd like a collaborator or a mentor to help me go through the process step by step.

I'm interested in hearing from people who would be interested and also on general thoughts both about the idea and about how to go about the actual programming.

Thanks!
