Prepare simulation of the model
This does not run the simulation, it only returns the simulation object. The object can then be run using run(max_time) command.
realtime: should the simulation be run in real time or not?
trace: should the trace of the simulation be printed?
gui: should the environment appear on a separate screen? (This requires tkinter.)
initial_time: what is the starting time point of the simulation?
environment_process: what environment process should the simulation use?
The environment_process argument should be supplied with the method environment_process of the environment used in the model.
kwargs are arguments that environment_process will be supplied with.
