  #  fix: move to read and share event/known_teams
  #    for all 1-n fixture files (no need to configure every time!!)

  logger.debug "Event #{@event.key} >#{@event.title}<"

  ### fix: use build_title_table_for ??? why? why not??
  ## @known_teams  = @event.known_teams_table

  @mapper_teams = TeamMapper.new( @event.teams )


  @known_grounds  = TextUtils.build_title_table_for( @event.grounds )
