  # A Person represents a person in a CITATION.cff file. A Person might have a
  # number of roles, such as author, contact, editor, etc.
  #
  # Person implements all of the fields listed in the
  # [CFF standard](https://citation-file-format.github.io/). All fields
  # are simple strings and can be set as such. A field which has not been set
  # will return the empty string. The simple fields are (with defaults in
  # parentheses):
  #
  # * `address`
  # * `affiliation`
  # * `alias`
  # * `city`
  # * `country`
  # * `email`
  # * `family_names`
  # * `fax`
  # * `given_names`
  # * `name_particle`
  # * `name_suffix`
  # * `orcid`
  # * `post_code`
  # * `region`
  # * `tel`
  # * `website`
