Use tree_evaluator class to walk the parse tree instead of rvalue
methods in the parse tree classes. Maintain a stack in the evaluator
class to accumulate results.
Pass pointer to evaluator to function objects and other classes as
needed for evaluation.
This is a work in progress that is not yet complete. The ultimate
goal is to move all evaluation into the tree_evaluator class instead
of spreading that work among many different classes. The global
pointer to the current evaluator should also be eliminated.
