/**
 * A violation that requires infinite time to manifest, such as a b-program
 * getting into an infinite loop which prevents it from achieving a required 
 * goal. These types of violations happen because of a "bad" cycle the the 
 * violating b-program's state graph. The exact definition of "bad" varies,
 * hence the "abstract base class with concrete sub-classes" design.
