fun lookupByValues(root: LookupTree<Element, Result>, argValues: List<A_BasicObject>, memento: Memento, lookupStats: LookupStatistics): Result
Given a List of A_BasicObjects, use their types to traverse the LookupTree. Answer the solution, a Result. Uses iteration rather than recursion to limit stack depth.
Return
The Result.
Parameters
root

arg
The input List of A_BasicObjects.
memento
A value potentially used for constructing Results in parts of the tree that have not yet been constructed.
