-#BUG, if *date comes after *team, the person's date is not set at all.
It needs re-setting at the end of the block.
- LoadSurvexFile() Creates a new current survexfile and valid .survexdirectory
The survexblock passed-in is not necessarily the 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.
