/**
 * A visitor for abstract syntax trees.
 * <p>
 * For each different concrete AST node type <i>T</i> there are
 * a pair of methods:
 * <ul>
 * <li><code>public boolean visit(<i>T</i> node)</code> - Visits
 * the given node to perform some arbitrary operation. If <code>true</code>
 * is returned, the given node's child nodes will be visited next; however,
 * if <code>false</code> is returned, the given node's child nodes will
 * not be visited. The default implementation provided by this class does
 * nothing and returns <code>true</code> (with the exception of
 * {@link #visit(Javadoc) ASTVisitor.visit(Javadoc)}).
 * Subclasses may reimplement this method as needed.</li>
 * <li><code>public void endVisit(<i>T</i> node)</code> - Visits
 * the given node to perform some arbitrary operation. When used in the
 * conventional way, this method is called after all of the given node's
 * children have been visited (or immediately, if <code>visit</code> returned
 * <code>false</code>). The default implementation provided by this class does
 * nothing. Subclasses may reimplement this method as needed.</li>
 * </ul>
 * </p>
 * In addition, there are a pair of methods for visiting AST nodes in the
 * abstract, regardless of node type:
 * <ul>
 * <li><code>public void preVisit(ASTNode node)</code> - Visits
 * the given node to perform some arbitrary operation.
 * This method is invoked prior to the appropriate type-specific
 * <code>visit</code> method.
 * The default implementation of this method does nothing.
 * Subclasses may reimplement this method as needed.</li>
 * <li><code>public void postVisit(ASTNode node)</code> - Visits
 * the given node to perform some arbitrary operation.
 * This method is invoked after the appropriate type-specific
 * <code>endVisit</code> method.
 * The default implementation of this method does nothing.
 * Subclasses may reimplement this method as needed.</li>
 * </ul>
 * <p>
 * For nodes with list-valued properties, the child nodes within the list
 * are visited in order. For nodes with multiple properties, the child nodes
 * are visited 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>
 * While it is possible to modify the tree in the visitor, care is required to
 * ensure that the consequences are as expected and desirable.
 * During the course of an ordinary visit starting at a given node, every node
 * in the subtree is visited exactly twice, first with <code>visit</code> and
 * then with <code>endVisit</code>. During a traversal of a stationary tree,
 * each node is either behind (after <code>endVisit</code>), ahead (before
 * <code>visit</code>), or in progress (between <code>visit</code> and
 * the matching <code>endVisit</code>). Changes to the "behind" region of the
 * tree are of no consequence to the visit in progress. Changes to the "ahead"
 * region will be taken in stride. Changes to the "in progress" portion are
 * the more interesting cases. With a node, the various properties are arranged
 * in a linear list, with a cursor that separates the properties that have
 * been visited from the ones that are still to be visited (the cursor
 * is between the elements, rather than on an element). The cursor moves from
 * the head to the tail of this list, advancing to the next position just
 * <i>before</i> <code>visit</code> if called for that child. After the child
 * subtree has been completely visited, the visit moves on the child
 * immediately after the cursor. Removing a child while it is being visited
 * does not alter the course of the visit. But any children added at positions
 * after the cursor are considered in the "ahead" portion and will be visited.
 * </p>
 * <p>
 * Cases to watch out for:
 * <ul>
 * <li>Moving a child node further down the list. This could result in the
 * child subtree being visited multiple times; these visits are sequential.</li>
 * <li>Moving a child node up into an ancestor. If the new home for
 * the node is in the "ahead" portion, the subtree will be visited
 * a second time; again, these visits are sequential.</li>
 * <li>Moving a node down into a child. If the new home for
 * the node is in the "ahead" portion, the subtree will be visited
 * a second time; in this case, the visits will be nested. In some cases,
 * this can lead to a stack overflow or out of memory condition.</li>
 * </ul>
 * <p>Note that {@link LineComment} and {@link BlockComment} nodes are
 * not normally visited in an AST because they are not considered
 * part of main structure of the AST. Use
 * {@link CompilationUnit#getCommentList()} to find these additional
 * comments nodes.
 * </p>
