I am still thinking about which dimension should partials belong. Should it be the leading dimension or the tilling dimension? It does feel right that partials should be in the...

Are there discontinuities or irregularities in the system?

Yes, indeed. I need to update this PR as well.

Yeah, this should make SDIRK methods more competitive against BDF methods and Rosenbrock methods as well.

 Here's the evolution of the convergence rate for this particular problem. I guess constant extrapolation isn't a bad guess to capture the plateaus.

 Here's theta vs model time.

The test failures seem unrelated.

Many of the regression tests might be too stringent.
