Created AgentSimulationStart which updates a demo.dsc file to demoUpdate.dsc file and sets up the Simulation environment. Sets up the grid and the obstacles, and location of the goal point.
May merge this with AgentAssignmentStart to have correct access to the Start/Goal states instead of hardcoding them in.
