  Here is an experiment for RLExperiments showing how to set up a simple independent learning with two players. (In the example, the roles of randomly choosing an action and taking create_policy -> DQN can be changed and they can also both try to approximate their Q values for action selection)

@HenriDeh, @jeremiahpslewis would you have a look? It is supposed to just be an example on how to use multiAgentPolicy.

I don't see a problem with the implementation but it needs to be added to the tests of RLExperiments like the other ones are. Otherwise we may not see that a change breaks this example and it will live there broken until someone notices.

I this what you intended to say here @HenriDeh ? Commit 82f77f4

FYI: rebased commit structure as it was messed up.

[HenriDeh]

Yes thank you. Gotta figure out why the CI fails now.

[Mytolo]

Finally, the pipeline should be correct. I needed to add some parts, but this is also helpful for other 3rd party environments once they need to be tested.

this should be solved now @HenriDeh ?

Hi @Mytolo, sorry for the delay, I was on vacations. You have conflicts to resolve then I can approve the PR for merging :)
