// MyProjectRunner instance. If the first MyProjectRunner instance was Shutdown-ed, the MySimulation instance is also
// cleared and any following Shutdown on other MyProjectRunner instances will cause freeze/inifnite hang.
// This code creates new MySimulation instance for each MyProjectRunner instance.
// Other solution could be to not have a MySimulation as a singleton in TypeMap configuration - and it could work just OK,
// because in BrainSim, the TypeMap's GetInstance on MySimulation is only on one place in MainForm. However, this may change
// in future or the change itself may have other consequences, so for now I pick this solution, as it is safer.
