  23. //| Purpose     : This class encapulates the data part of a TreeNode.          |
  24. //|               This 'encapsulation' is necessary because the 'data' portion |
  25. //|               could really be 'data', but it could also be another         |
  26. //|               TreeNode.                                                    |
  27. //| Usage note  : Methods in this class are accessible from friends and        |
  28. //|               relations only. You cannot instantiate from this class.      |
