- Obscure bug in the *team inheritance and rootblock initialization needs tracking down,
probably in the team cache which should NOT be global, but should be an instance variable of
LoadingSurvex
- Lots to do to cut down on unnecessary .save() calls to avoid hitting the db so much. Should
speed it up noticably.
- Learn to use Django .select_related() and .prefetch_related() to speed things up
https://zerotobyte.com/how-to-use-django-select-related-and-prefetch-related/
- LoadSurvexFile() Creates a new current survexfile
The survexblock passed-in is not necessarily the survex parent. FIX THIS.
- When Olly implements LEG in the 'dump3d --legs' utility, then we can use that to get the length of
all the legs in a survex block instead of adding them up oursleves. Which means that we can
ignore all the Units and offset stuff, that troggle will work with survex files with backsights,
repeated readings from distox etc.. Not actually useful for pre 2022 survey data,
but good future-proofing.
Also it will be a tiny bit more accurate as these leg lengths are after loop closure fixup.
