Use new Discrete Event Scheduling in examples

Open for contributions!

Now that the Discrete Event Scheduler (DEVS) is released as experimental in Mesa 2.3.0, it would be interesting if we can use it in examples.

• Current code implementation: mesa/experimental/devs
• Original PR: https://github.com/projectmesa/mesa/pull/2066
• Original discussion: https://github.com/projectmesa/mesa/discussions/2032

All three mesa benchmark models already use devs, so those changes could be ported over.

The approach for this would generally be:

• Read up on DEVS
• Go through the Mesa examples and seek opportunities where the DEVS could simplify or improve things.
• Open a Discussion on mesa-examples proposing your changes
• Implement them and open a PR here

The nuance here being that applying the DEVS is not a goal to be implemented as much as possible, but a means that could make some model (parts) more elegant, efficient, readable and/or performant.

Start by reading the DEVS implementation in mesa/experimental/devs and the existing usages in the benchmarks directory. Review the Mesa examples for cases where discrete event scheduling could improve readability, efficiency, or performance, then propose candidates in a mesa-examples Discussion before implementing anything. Done means an agreed example change is implemented and submitted as a PR.
