The CVODES constraint handling (see also #2327) would also allow us to enforce conservation laws, and probably make our code quite a bit simpler.
To be discussed whether we'd want to keep the curre…

#### Summary:
@syclik claims that if we try to build all the models in `stan-dev/stan/test-models/good` for `fvar` that they will break because second-order autodiff isn't complete.

My ode function is well-suited for `SX`, and when I integrate with CVODES it is on the order of 100x faster with `SX` than with `MX`.
I added a lookup table operation which forces me to use `MX`, a…
