enhancement - on start up - throw error if script bombs out

[John D. Pope]

usually just running python will uncover exceptions - but it would be great to propagate this out to console.

maybe we can just add
import logging

except Exception as err:
failed = True
log(json.dumps(generate_exception_event(err)))
logging.error(err)

this helps propagate error to console

this should be merged....
