- refactor everything with some urgency, esp. LoadLogbookForExpedition()
- refactor everything with some urgency, esp. parse_logbook_for_expedition()
- remove the TROG things since we need the database for multiuser access? Or not?
- break out the code that hits the database from that which parses the logbook
so that the file-reading and parsing can be parallelized, while writing to the
database remains serialized (sqlite is single-user).
- profile the code to find bad repetitive things, of which there are many.
- attach or link a DataIssue to an individual expo (logbook) so that it can be found and deleted
- far too many uses of Django field dereferencing to get values, which is SLOW
- rewrite to use generators rather than storing everything intermediate in lists - to reduce memory impact.
