Change the simulation loop to mimic a co-simulation framework.
Change the simulation loop to mimic a co-simulation framework.

For now, this is a trivial explicit coupling co-simulation with all modules taking one fixed step equal to the communication interval.
The modules are given a chance to exchange data (by calling their respective Update functions), after which they are simulated to the next time (by calling their respective Advance functions).
