docs: def kana_romaji_lt(romaji, *kana):
      '''
      Generates a lookup table with the kana characters on the left side
      and their rōmaji equivalents as the values.
  
      For the consonant-vowel (cv) characters, we'll generate:
  
         {u'か': ('ka', 'k', 'k', 'ā'),
          u'が': ('ga', 'g', 'g', 'ā'),
          [...]
  
      Multiple kana character sets can be passed as rest arguments.
