Is there a minimal example of what a new HMC algorithm needs to implement to be able to fit into this framework?

This is not so much an issue as a request for advice. I have developed a new HMC algorithm that doesn't use gradients, integrators or compute trajectories but uses a specific Hamiltonian form (that isn't separable). I would like to use AdvancedHMC to compare its performance with all the tried and tested old HMC algorithms. Is there a minimal template for what I need to implement to interface with the rest of AdvancedHMC.jl? Or should I try to interface with more general MC samplers, except that I provide my own function for new proposals? Thanks for any advice.
