class_docstr: A data frame class, with only the methods required by the interchange
  protocol defined.
  
  A "data frame" represents an ordered collection of named columns.
  A column's "name" must be a unique string.
  Columns may be accessed by name or by position.
  
  This could be a public data frame class, or an object with the methods and
  attributes defined on this DataFrame class could be returned from the
  ``__dataframe__`` method of a public data frame class in a library adhering
  to the dataframe interchange protocol specification.
