How do I switch between naive, adjoint and ACA methods

[OezMe]

After reading Adaptive Checkpoint Adjoint Method for Gradient Estimation in Neural ODE, I decided to try out the 3-body problem. I managed to make it run after encountering some technical issues on my side.

Despite reading the ReadMe and the paper and looking at the code, I cannot tell how I can swap between the methods the papers mentioned or how I can tell what is simulated? NODE or ODE? Naive, Adjoint or ACA?
