/**
 * A simple visitor, based upon the classic double dispatch method, for walking GrammarAST trees resulting from
 * parsing ANTLR grammars. There is also the GrammarTreeVisitor.g tree grammar that looks for subtree patterns and
 * fires off high-level events as opposed to "found node" events like this visitor does. Also, like all visitors, the
 * users of this interface are required to implement the node visitation of the children. The GrammarTreeVisitor
 * mechanism fires events and the user is not required to do any walking code.
 * ```
 *     GrammarAST t = ...;
 *     GrammarASTVisitor v = new ...;
 *     t.visit(v);
 * ```
