    public static void doExtendTraits​(ClassNode cNode, SourceUnit unit, CompilationUnit cu)
    Given a class node, if this class node implements a trait, then generate all the appropriate code which delegates calls to the trait. It is safe to call this method on a class node which does not implement a trait.
    Parameters:
      `cNode` - a class node
      `unit` - the source unit
