How do we reset the environment during training? Looking at these docs and elsewhere I can see how to implement OnEpisodeBegin() on my agents and how to call EndEpisode() for each of them as each finishes, and I can see how to subscribe to the Academy.Instance.OnEnvironmentReset event so that I can reset the overall environment when it actually does reset, however I cannot see how to cause the environment to reset. My current use case is that I have up to several agents on a "team". When all on a team have died, then the game ends and I need to reset the environment. As each of them individually dies, then his own EndEpisode() is called and that's fine. But once they have all died, I need to reset everything (including non-agent objects in the environment to put things back to how they should be at the start of a game). It looks like Academy used to have something like a Done() method on it. I'm using 0.15.1 and don't see anything like that. So how does one reset the environment now? Thanks.
