Class too deep in inheritance tree

Reports classes that are too deep in the inheritance hierarchy.

Classes that are too deeply inherited may be confusing and indicate that a refactoring is necessary.

All superclasses from a library are treated as a single superclass, libraries are considered unmodifiable.
