Add that it should match the DiffEq interface. the Shooting method is an example to follow for how to do this.

About the ForwardDiff jacobian: I am assuming this is applied to f, rather than Phi?
What will be the alternative if f does not accept general Real types but only Float64 (e.g.). Probably finite-differencing. And since it is only applied to f rather than Phi this should actually be fine. Probably worth including this as well.

Yeah, having a different setting use Calculus.jl would be recommended. The Jacobian should be built from the Jacobian of f anyways, since that's what the user would know how to set in the case an analytical Jacobian is known. So at the bottom it's either Calculus.jl or ForwardDiff.jl on f, then building the Jacobian from there.

I think finite difference has moved to a separate package - but you are right that is all that is needed

FiniteDiff.jl, but I don't think it's ready or registered.
