      COPY a ctx (I'm deliberately not using copy constructor) to avoid
      confusion with creating node with parent. Does not copy children
      (except error leaves).
      This is used in the generated parser code to flip a generic XContext
      node for rule X to a YContext for alt label Y. In that sense, it is not
      really a generic copy function.

      If we do an error sync() at start of a rule, we might add error nodes
      to the generic XContext so this function must copy those nodes to the
      YContext as well else they are lost!

      Print out a whole tree, not just a node, in LISP format
       (root child1 .. childN). Print just a node if this is a leaf.
       We have to know the recognizer so we can get rule names.
