Start conversion to TEISimple
The Fontane-TEI is far too complex to display all information in the planned book or edition view on the website. Therefore we break it down into a simpler format. We chose TEISimple in order to be able to re-use TEISimple's processing models and to display the edition view in the DFG Viewer.
This is just the initial commit for the module with non-working tests -- for some reason inspect:module-functions doesn't find any functions. Even the examples provided on exist-db.org don't seem to work in exist-db 4.2.0.
