Preparing a GraphRyder demo for the review meeting

@melancon suggested this, and I agree.

Would it make sense to prepare a simpler instantiation of GraphRyder? Some of the features are not fully developed yet, and anyway we do not have the time for an all-round demo. I was thinking: one example of synthesis, one of exploration. We need @Amelia 's help for the latter. 

In terms of code, I imagine a version of the dashboard with only one or two tabs. Anything that can be done to improve the aesthetics is also welcome. 

If you all agree (especially @Jason Vallet ) we could make it a GitHub milestone, agree on what to do before the demo, encode the to-do as issues, and let Jason work his magic.
