    - #### supportsNeverEndingMoveSelector

          boolean supportsNeverEndingMoveSelector()

      Returns:
        true if it can be combined with a `Selector.isNeverEnding()` that returns true.

    - #### addMove

          void addMove​(LocalSearchMoveScope moveScope)

      Parameters:
        `moveScope` - never null

    - #### isQuitEarly

          boolean isQuitEarly()

      Returns:
        true if no further moves should be selected (and evaluated) for this step.

    - #### pickMove

          LocalSearchMoveScope pickMove​(LocalSearchStepScope stepScope)

      Parameters:
        `stepScope` - never null
      Returns:
        sometimes null, for example if no move is selected
