-/** 
-  Class TNode is an implementation of the AST interface
-  and adds many useful features:
-
-  It is double-linked for reverse searching.
-  (this is currently incomplete, in that method doubleLink() must
-  be called after any changes to the tree to maintain the 
-  reverse links).
-
-  It can store a definition node (defNode), so that nodes such
-  as scoped names can refer to the node that defines the name.
-
-  It stores line numbers for nodes.
-
-  Searches for parents and children of a tree can be done
-  based on their type.
-
-  The tree can be printed to System.out using a lisp-style syntax.
