Nested class improvements - Fixed inconsistency in handling C++ nested classes - sometimes they were treated as forward declarations, other times as if C nested struct was parsed. Added the nestedworkaround feature for C++ nested class handling. Document improved nested class handling. Numerous C and C++ nested struct/class/union test cases added.
