Implemented writer and serializer for simulations.
Preserve original paths of simulation scenes to keep relative paths in simulation scenes working.
Clarified interfaces of Simulation and SimulationService and moved ExportMitkVistor from plugin to module.
Implemented scheduler for pseudo-parallel simulation runs.
Implemented fair pseudo-parallel simulation runs with weighted round robin scheduling.
Added missing breaks in switch statement.
Moved time measurement into Simulation class and Scheduler to SimulationService.
Added live simulation scene tree view.
Implemented simulation interactor (beta) and simulation scene "data manager".
Continued implementing simulation interaction (still beta).
