# verify_default_data_existence()
#
# Purpose: This verifies that specific data in LAI exists or creates them if they don't exist.
#          This is used in the regular login page and in command_line_report, and is called
#          each time Sawmill runs (technically, each time it creates a GlobalStruct object).
