Version 0.3.3

• New organisation() class to hold the requirements of the organisation.
  For the time being this is hard-coded to the Research Institute for Nature
  and Forest (INBO).
• Author affiliations must match one of the affiliations set in
  organisation().
  The membership of an author is determined by their e-mail or their
  affiliation.
  This is checked when creating or using author information and when updating
  citation information.
• read_checklist() looks for checklist.yml in parent folders when it can't
  find it in the provided path.
• validate_orcid() checks the format and the checksum of the ORCID.
• Add vignette("folder", package = "checklist").
