> Using the Visitor pattern allows for a cleaner implementation of toString().
> I have a patch which will remove toString() from all AST classes, and replace it with a single toString() in "SimpleNode" which delegates to a ToStringVisitor to build the String efficiently.  
> This patch can also be used as an example of how to move other business logic out of the AST classes into their own visitor classes.
