Draft status while doing performance comparisons.

This branches of offfeature/rk_defaults with feature/min-err merged in.

Current adaptivity controller changes:

  • No deadzone
  • Bias: 1.0
  • Safety factor: 0.9
  • Adjustment: 0
  • I controller for ARKStep and ERKStep (to be changed based on Sylvia’s testing)

FYI, after discussing this topic with Sylvia, I realized that in fact I should have implemented both the H312 and H0321 controllers - while I included both in the FAQ, I'd only implemented the simplified constructor for H312. I just added H0321 as well to complete the implementation.
