public interface ReverseAbstractInterpreter
This interface defines what reversed abstract interpreters provide.

Abstract interpretation is the process of interpreting a program at an abstracted level (such as at the type level) instead of the concrete level (the flow of values). This reversed abstract interpreter reverses the abstract interpretation process by knowing the outcome of some computation and calculating a preciser view of the world than the view without knowing the outcome of the computation.
