'''Reads all the cave description data by parsing the xml files (stored as e.g. :EXPOWEB:/cave_data/1623-161.html )

This is the first import that happens after the database is reinitialised. 
So is the first thing that creates tables.

 - Cannot use Edit This Page for pendingcaves.txt_edit as Edit This Page is expecting an html file.
   So we will need a separate file-editing capability just for this configuration file ?!
   
- crashes on MariaDB in databasereset.py on server when deleting Caves and complains Area needs a non null parent, But this is not true.
  The only solution we have found is to let it crash, then stop and restart MariaDB (requires a logon able to sudo)
  and then restart the databasereset.py again. (status as of July 2022)
