Generic method decorator for logging calls under the
assumption that return=GOOD, exception=FAIL. The method
determines parameters as:
subdir = self.subdir if it exists, or None
operation = "class name"."method name"
status = None on GOOD, str(exception) on FAIL
The object using this method must have a job attribute
for the logging to actually occur, otherwise the logging
will silently fail.
Logging can explicitly be disabled for a call by passing
a logged=False parameter

# in success/failure logging
