Make a distinction between main, parsed and auxfiles in md, es (and postges)
This should allow to make a difference between:
- mainfile
- parsedfiles
- auxfiles
This should be reflected in the repository data:
- metadata on the disc
- repository-section in the archives
- search index
There is not distinction in the CoE repository db or the CoE search index. The repo GUI has to make this up on the fly.
The parser might use the AnciliryParser with seems to write calculation_file_uri
(same as simple parser). This will not be consistent over all parser. Same with start/finish sessions. Those are only called by mainparsers as far as I can see.
