  ===== Interface `Results`
  
  The `Result` interface is used by all clients 
  (especially `Reporter` subclasses, graphical and command-line
  clients) to access checking results. It consists of three distinct APIs for
  overall `RunResults`, single-page results (`PageResults`) and single-check results

  | results for potentially many Html pages/documents.
  
  | Single-Page-Results
  | results for a single page
  
  | Single-Check-Results
  | results for a single type of check (e.g. missing-images check)
  
  | Finding

  and (planned for future releases) the responsible html element.
