 * The DummyEObject is used to build a stack of dummy objects when descending by
 * tail recursion into left recursive rules. They cache the setting information
 * for initializing concrete EObject instances.
 * When the tail descent is finished this stack is reduced in reverse order. The
 * EObjects are created using the setting informations and a containment hierarchy
 * is build using the left recursive EStructuralFeature.
