def find_key_n_title( values )  # NB: returns ary [attribs,more_values] / two values

  ## fix: add/configure logger for ActiveRecord!!!
  logger = LogKernel::Logger.root

  ### todo/fix: allow check - do NOT allow mixed use of with key and w/o key
  ##  either use keys or do NOT use keys; do NOT mix in a single fixture file

  ### support autogenerate key from first title value

  # if it looks like a key (only a-z lower case allowed); assume it's a key
  #   - also allow . in keys e.g. world.quali.america, at.cup, etc.
  #   - also allow 0-9 in keys e.g. at.2, at.3.1, etc.

  # fix/todo: add support for leading underscore _
  #   or allow keys starting w/ digits?

  ## check title_col for grade (e.g. ***/**/*) and use returned stripped title_col if exits
  grade, title_col = find_grade( title_col )

  # NB: for now - do NOT include default grade e.g. if grade (***/**/*) not present; attrib will not be present too
  if grade == 1 || grade == 2 || grade == 3  # grade found/present
    logger.debug "   found grade #{grade} in title"
    attribs[:grade] = grade
  end

  ## fix/todo: add find parts ??
  #  e.g. ‹Estrella› ‹Damm› Inedit
  #    becomes =>   title: 'Estrella Damm Inedit'  and  parts: ['Estrella','Damm']

  ## title (split of optional synonyms)
  # e.g. FC Bayern Muenchen|Bayern Muenchen|Bayern
  titles = title_col.split('|')

  attribs[ :title ]    =  titles[0]

  ## add optional synonyms if present
