  /**
      @brief A special vertex that allows to merge several inputs.

      A special vertex that allows to merge several inputs. Mergers have two modes: The normal,
      round-based merging mode and a "wait & merge all" mode. In round-based mode, a merger
      first takes the first files of each incoming file list and merges them into a list (which
      has as many elements as the merger has incoming edges).

      In "wait & merge all" mode, the merger first waits for all upstream mergers to finish all
      their merging rounds and then merges all collected files from all merging rounds for all
      incoming edges into one single list and calls the next tool with this list of files as input.
