abc_inference is not included but exported #248
Description
Hello, it seems that new version doesn't support approximate bayesian computation any more. However, in main DiffEqBayes.jl, abc_inference is exported. Also, codes of example of README implies that abc-inference depends on DynamicHMC.jl, should it be dependent on ApproxBayes.jl?
It seems that ApproxBayes.jl is not maintained. I forked it and simply bump the version. include("abc_infernce.jl") and test abc.jl in DiffEqBayes.jl. It still works. Maybe it is a solution for someone who wants to use approximation bayesian computation.
