          ScoreDirector<Solution_> clone()

      Clones this `ScoreDirector` and its `working solution`. Use `ScoreDirector.getWorkingSolution()` to retrieve the `working solution` of that clone.

      This is heavy method, because it usually breaks incremental score calculation. Use it sparingly. Therefore it's best to clone lazily by delaying the clone call as long as possible.

      Parameters:
        `allChangesWillBeUndoneBeforeStepEnds` - true if all changes will be undone

    - #### assertExpectedWorkingScore

          void assertExpectedWorkingScore(Score expectedWorkingScore,
                                          Object completedAction)

      Used to assert that skipping `ScoreDirector.calculateScore()` (when the score is otherwise determined) is correct.

      Asserts that if all `VariableListener`s are forcibly triggered, and therefore all shadow variables are updated if needed, that none of the shadow variables of the `working solution` change, Then also asserts that the `Score` calculated for the `working solution` afterwards is equal to the parameter `expectedWorkingScore`.

      Used to assert that the shadow variables' state is consistent with the genuine variables' state.

      Parameters:
        `expectedWorkingScore` - never null
        `completedAction` - sometimes null, when assertion fails then the completedAction's `Object.toString()` is included in the exception message

      Asserts that if the `Score` is calculated for the current `working solution` in a fresh `ScoreDirector` (with no incremental calculation residue), it is equal to the parameter `workingScore`.

      Furthermore, if the assert fails, a score corruption analysis might be included in the exception message.

      Parameters:
        `workingScore` - never null
        `completedAction` - sometimes null, when assertion fails then the completedAction's `Object.toString()` is included in the exception message
