you have to set the tolerance really low to test the difference here, since finite difference is really sensitive.

Ah OK. However, I guess it does not matter at the moment - the values are off by multiple orders of magnitude, and even the signs do not match.

I added tests similar to the ones in https://github.com/JuliaDiffEq/OrdinaryDiffEq.jl/blob/master/test/interface/ad_tests.jl. Unfortunately they show that AD doesn't work (as suspected in #133).
