Detailed Description
ExprTreeVisitor is an abstract base class used to implement the Visitor pattern on ExprTree Nodes.
The ExprTree::acceptVisitor method will call visitExprTreeBefore, visitExprTreeAfter, and acceptVisitor on the root node. If you want to traverse other nodes then you must call acceptVisitor on children nodes when appropriate. See EvalToConstVisitor::visitOpNode for an example.
Memory Management: It is assumed that the concrete visitors will NOT keep references to expression tree nodes and that the expression tree will not be deallocated while an ExprTreeVisitor is visiting an ExprTree. Concrete visitors should also never take the address of a Node or ExprTree and pass it to a method that requires an OA_ptr<Node>.
