[Users] The veraPDF Processor API - Unknown classes in Example

Hi,

the example of "The veraPDF Processor API" (see http://docs.verapdf.org/develop/processor/ ) uses classes I don't know where to retrieve them from: - Config - ProcessorImpl - ProcessingResult

To which package(s) does these classes belong to?

Which artifact contains these classes and how can I retreive this artifact?

Best regards rpf
