-/**
- * Concrete superclass and default implementation of an AST subtree matcher.
- * <p>
- * For example, to compute whether two ASTs subtrees are structurally
- * isomorphic, use <code>n1.subtreeMatch(new ASTMatcher(), n2)</code> where
- * <code>n1</code> and <code>n2</code> are the AST root nodes of the subtrees.
- * </p>
- * <p>
- * For each different concrete AST node type <i>T</i> there is a
- * <code>public boolean match(<i>T</i> node, Object other)</code> method
- * that matches the given node against another object (typically another
- * AST node, although this is not essential). The default implementations
- * provided by this class tests whether the other object is a node of the
- * same type with structurally isomorphic child subtrees. For nodes with
- * list-valued properties, the child nodes within the list are compared in
- * order. For nodes with multiple properties, the child nodes are compared
- * in the order that most closely corresponds to the lexical reading order
- * of the source program. For instance, for a type declaration node, the
- * child ordering is: name, superclass, superinterfaces, and body
- * declarations.
- * </p>
- * <p>
- * Subclasses may override (extend or reimplement) some or all of the
- * <code>match</code> methods in order to define more specialized subtree
- * matchers.
