// is the abstract "Visitor". This class is the abstract base class
// for visitors that traverse the AST_<node> classes. Other abstract
// classes for C++ code generation, Java code generation, or IfR
// administration, for example, can be derived from this class and
// be the root of their own subtree of specialized visitor classes.
