This is creating and linking a Placeholder logbookentry dated 1st Jan. in the relevant

year. This is pointless but it is needed because found_by is a ForeignKey in the db
|
||
and we can't be arsed to fudge this properly with a null.(July 2020)
|
||
|
||
Linking to a passage in a SVX file might be more interesting as the QM does sometimes
|

have the passage name, e.g. in 204/qm.csv

C2000-204-39 B Tree Pitch in Cave Tree treeumphant.28 Gosser Streamway

The CSV file does not have the exact date for the QM, only the year, so links to

survex files might be ambiguous. But potentially useful?"""
