/**
 * <p>
 * This class provides a convenient behaviour-only extension mechanism for the ASTNode hierarchy. If
 * you feel like you would like to add a method to the ASTNode hierarchy (or a subtree of the
 * hierarchy), and you want to have different implementations of it at different points in the
 * hierarchy, simply create a HierarchicalASTVisitor representing the new method and all its
 * implementations, locating each implementation within the right visit(XX) method. If you wanted to
 * add a method implementation to abstract class Foo, an ASTNode descendant, put your implementation
 * in visit(Foo). This class will provide appropriate dispatch, just as if the method
 * implementations had been added to the ASTNode hierarchy.
 * </p>
 *
 * <p>
 * <b>Details:<b>
 * </p>
 *
 * <p>
 * This class has a visit(XX node) method for every class (concrete or abstract) XX in the ASTNode
 * hierarchy. In this class' default implementations of these methods, the method corresponding to a
 * given ASTNode descendant class will call (and return the return value of) the visit(YY) method
 * for it's superclass YY, with the exception of the visit(ASTNode) method which simply returns
 * true, since ASTNode doesn't have a superclass that is within the ASTNode hierarchy.
 * </p>
 *
 * <p>
 * Because of this organization, when visit(XX) methods are overridden in a subclass, and the
 * visitor is applied to a node, only the most specialized overridden method implementation for the
 * node's type will be called, unless this most specialized method calls other visit methods (this
 * is discouraged) or, (preferably) calls super.visit(XX node), (the reference type of the parameter
 * must be XX) which will invoke this class' implementation of the method, which will, in turn,
 * invoke the visit(YY) method corresponding to the superclass, YY.
 * </p>
 *
 * <p>
 * Thus, the dispatching behaviour achieved when HierarchicalASTVisitors' visit(XX) methods,
 * corresponding to a particular concrete or abstract ASTNode descendant class, are overridden is
 * exactly analogous to the dispatching behaviour obtained when method implementations are added to
 * the same ASTNode descendant classes.
 * </p>
