ControlSet

ControlSet is an abstraction over the various runtime-only parts of model state. For instance, what output is shown to the user? What does the interface look like for the user. At the moment, it is likely it will only be needed for NetLogo UI, but there's a chance it could also be useful for some aspect of Headless in the future.

Methods on this class should perform the "correct" action regardless of whether they are called from the job or swing event thread. Future is used because these computations may be asynchronous.
