docs: Find distinct values for the given field and count the number of
      occurrences. Returns a :class:`dict` mapping values to counts. E.g.::
  
          >>> import petl as etl
          >>> table = [['foo', 'bar'],
          ...          ['a', True],
          ...          ['b'],
          ...          ['b', True],
          ...          ['c', False]]
          >>> etl.valuecounter(table, 'foo')
          Counter({'b': 2, 'a': 1, 'c': 1})
  
      The `field` argument can be a single field name or index (starting from
      zero) or a tuple of field names and/or indexes.
