Logging levels are stacked, with a chosen logging level also triggering all
levels below it; choosing a logging level of DEBUG will cause all DEBUG,
INFO & WARN levels to be output, choosing a logging level of WARN will only cause
WARN levels to be output.
They are arranged this way to allow additional items to be added if required.
