This class contains the state of an 'not' operator in the evaluation state tree.
The not operator inverts the truth of the subexpression under it. It defaults to being true rather than
being false at Startup. True at Startup means it will generate an event on newState such that parent expressions
may turn true. It turns permenantly false when it receives an event from a subexpression and the subexpression
quitted. It indicates the false state via an evaluateFalse call on its parent evaluator.
