Detailed Description

Base class for all parse tree nodes. The node classes all derive from node_impl. Each derived class overrides print_node(), for debugging and evalute_node() to evaluate the node. A few classes also override evaluate_string(), but most classes can inherit the node_impl::evaluate_string implementation, which prints the result of calling evaluate().
