SystemState
public class SystemState implements Storable,State(Code)
the class that encapsulates not only the current execution state of the VM (the KernelState), but also the part of it's history that is required by JVM to backtrack, plus some potential annotations that can be used to control the search (i.e. forward/backtrack calls)
