#   As we want to create jobs for individual tables, due to the limitation of the 
#   ci "language" we would need to create many many blocks of code for each table in 
#   .gitlab-ci.yml, which would be very annoying. This script, combined with the ci-template
#   can be used to procedurally generate a yaml file containing the necessary job specs
#   for the table summary and check delta jobs, for each table specified in the 'tables' list
