caves - read in the caves
logbooks - read in the logbooks
people - read in the people from folk.csv
QMs - read in the QM csv files (older caves only)
reinit - clear database (delete everything) and make empty tables. Import nothing.
scans - the survey scans in all the wallets
survex - read in the survex files - all the survex blocks
survexpos - just the Pos out of the survex files (not part of reset)
tunnel - read in the Tunnel files - which scans the survey scans too
resetend - (archaic?)
writecaves - *disabled* (archaic?)
autologbooks - read in autologbooks (what are these?)
dumplogbooks - write out autologbooks (not working?)
syncuser - needed after reloading database from SQL backup
surveys - read in scans by expo, must run after "people". Not used.
test - testing...
and [runlabel] is an optional string identifying this run of the script
in the stored profiling data 'import-profile.json'
caves and logbooks must be run on an empty db before the others as they
set up db tables used by the others.
