          public TraitComposer()

  - ### Method Detail

    - #### doExtendTraits

          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
