For all OrdinaryDiffEq.jl methods, an initialization scheme can be set with a
common keyword argument `initializealg`. The choices are:

- `CheckInit`: Check that the provided initial conditions satisfy the equation;
if not, error. This avoids the need for nonlinear solution, as well as avoiding
changing the provided initial conditions.
- `BrownFullBasicInit`: For Index-1 DAEs implicit DAEs and semi-explicit
DAEs in mass matrix form. Keeps the differential variables constant. Requires
`du0` when used on a `DAEProblem`.
