Parametrically stress testing examples/models?

[esba1ley]

Thought:

Today I hooked up the fbar Open-SDFast example to the general simulation analysis driver Dakota, and I did a 512-case Latin Hypercube Sampling of varying all the linkage masses (not the inertias... so there's some weirdness there) and the viscous damping at the crank by +/- 10% uniformly distributed of the nominal values, and I got a bifurcation in the result for going around a second rev in a few cases:

Do we want to set up tests that perturb parameters across some ranges for more thorough testing than just single time trace tests?
