Short description of the author problem in Korp.
1. presentation issue in Korp: Surname and family name are not presented one after the other
  ==> something to debug in Korp

2. many documents registered with our corpus lack the info on authors:
 ==> huge amount of "UNKNOWN" labels

3. as noted by Jussi, SDA and Diedut get wrong author labels because they are not split by
 article

4. what about the instances with several authors? Only the first is shown by Korp and/or
registered with the cqp?

5. Korp-implementation issue: in the current version, it is not possible
just to show the author without giving the possibility to search for 
(contrary to what we agreed upon). I have proposed a change from this implementation
at the meeting in Gothenburg last year. I have to check possible changes.
