Provides an abstract class for accurate modeling of flow through output
iterators. To use this QL library, create a QL class extending
IteratorReferenceFunction with a characteristic predicate that selects the
function or set of functions you are modeling. Within that class, override
the predicates provided by
AliasFunction to match the flow within that
A function which takes a container and returns an iterator over that container.
