Changes

Summary

1. Core: Preparation for the overhaul of the ConstructorReferencesCheck and the generation of $super-Methods: - Moved analysis of the inheritance trees from the Generator-project to a new task in the Core-project: AnalyzeInheritanceTreesTask. The results of this task (a map that shows which class has to call constructors of which super classes) is now part of the AST-Model, thus - Added a new field to the AST-Model (Model.java) which holds the result of the new AnalyzeInheritanceTreesTask. - Added methods to retrieve the new field from the Model and to put pairs of the form (Type, List<Type>) into the new map. - Integrated the new Task in SyntaxCheckAbstract - Adjusted a test case (It asserted an exception that does not occur due to the changes made in SyntaxCheckAbstract. Instead another Exception occurs now that is being asserted).
