# This handles moving around and managing files on Anvil! nodes, DR hosts and Striker dashboards.
# 
# When this is called (periodically by the daemon of after an upload / ISO generation);
# - 1. Check 'incoming/' for files. For any found, generate an md5sum and see if the file name and sum match 
#      anything in the database from any host;
#      - If so, update/add an entry in 'file_locations'
#      - If not, create a new entry in 'files' and then add the first entry in 'file_locations'
# - 2. Check 'file_locations' for any files on this system, and verify they exist still. 
#      - If not, check the other files for one with a matching md5sum. If found, handle as a rename.
#      - If not found at all, search for the file according to the search rules and copy to here if found.
#      - If not found anywhere, remove it from 'file_locations' and send an alert.
#      - If found, check the size. If it differs, recalculate the md5sum.
# - 3. If called with '--rename --file <filename> --to <newname>', rename the file and update 'files'.
# - 4. If called with '--delete', remove from 'file_locations' and then remove from the local storage.
