org.optaplanner.core.impl.heuristic.move.Move
A Move represents a change of 1 or more planning variables of 1 or more planning entities in the working {@link Solution}.
Usually the move holds a direct reference to each planning entity of the {@link Solution}which it will change when {@link #doMove(ScoreDirector)} is called.On that change it should also notify the {@link ScoreDirector} accordingly.
A Move should implement {@link Object#equals(Object)} and {@link Object#hashCode()}.
An implementation must extend {@link AbstractMove} to ensure backwards compatibility in future versions. @see AbstractMove
