/**
* 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.
