• created extension method GetObjectGraphObjects for objects
• created IStatefulItem interface, which means an object has a state which can be initialized and cleared
• after an algorithm stopped, all objects of the algorithm-objectgraph with the type IStatefulItem are cleared
• on prepare, all IStatefulItem objects are initialized
