Description

EDIT: The issue title has been edited to showcase that there is now a formal solution on how to differentiate ABMs, see this comment. Implementing a model that integrates with this as one of our "Integration Examples" would be lovely. :)

Perhaps we can even provide some function(s) that make integration easy, as we did when we were writing the integration example with CellListMap.jl (#659 )

I have tried to use Zygote.jl to differentiate some random and small ABMs. But I get many different errors. Are there data structures that are not supported by Zygote yet? A differentiable ABM would be amazing and allowing to solve many problems.

Contributor guide

Research direction
Review the comment referenced in the issue (https://github.com/JuliaDynamics/Agents.jl/issues/175#issuecomment 1282249051) for the formal solution. Study the existing integration example with CellListMap.jl (#659) to understand the pattern. Propose a new integration example using StochasticAD.jl or another AD framework for differentiable ABMs.
