Changes

Summary

1. Core: - Altered AnalyzeInheritanceTreesTask to skip such sum types which have the root class of the viewed inheritance tree as element as these don't have to be instantiated explicitly. - Altered ReferencedConstructors check to replace sums that do not match the criteria above to be replace by the sum type element mentioned in the corresponding constructor as a sum type itself cannot be instantiated but a constructor call to one of its elements must exist if the caller is not part of the sum type itself. Generator: - Sorted the ConstructorCallGenerationTask into the generation procedure. - Moved the generation of $super/setThis-methods and constructors to the ConstructorCallGenerationTask and removed their counterparts from the OperationAttributeTransformer and the GenInterfaceWithImplClass. - Implemented the generation of parameterized $super-Methods per constructor. - Fixed test cases that expected generated parts after the OperationAttributeTransformer which are not being generated by it anymore.
