Off/on/level setting for debug logging #18
Description
There should be a flag or log-level setting (perhaps defaulting to false/"errors-only") to control the console.log message generated by SerialHub front-end (controllable by back-end).
If viewed in a FATAL / ERROR / WARN / INFO / DEBUG / TRACE log-level scheme:
FATAL=ERROR=WARN: Any error result that we can log.
INFO (default): Successful Connect/Disconnect and other "rare" successful actions.
DEBUG=TRACE: Successful read/write or other "frequent" activities
The logging of each and every message sent/received is the primary thing to suppress, other messages are sparse and almost always potentially relevant to the end-user. Essentially a "debug" or "verbose" boolean could suffice.
