 * A cheap, context-insensitive thin slicer based on reachability over a custom SDG.

 * <p>This is a prototype implementation; not tuned.
 *
 * <p>Currently supports backward slices only.
 *
 * <p>TODO: Introduce a slicer interface common between this and the CS slicer. TODO: This hasn't
 * been tested much. Need regression tests.
