Sumatra integration

[rgerkin]

Use Sumatra for managing and tracking simulations associated with test runs. This would probably involve using the @capture decorator on the implementations of whatever functions run the model.

@apdavison Do you have any thoughts on this?

[apdavison]

I'll have a think and get back to you.

First thought is that you would want to capture not only the simulation, but also any data analysis and score calculation steps, so Test.judge() is perhaps the place to put this. On the other hand, I imagine the different stages of a test could run on different (local or remote) machines, so perhaps they should be instrumented separately.
