Have removed the SimulatorState base class, and instead replaced with the SimulationDatacontainer class from opm-common. The SimulatorState objects were typcially created with a default constructor, and then explicitly initialized with a SimulatorState::init() method. For the SimulationDataContainer RAII is employed; the init( ) has been removed - and there is no default constructor.
