v0.15.0: Log class update with split up class with Logger sub class for pool/fork/thread worker setup

This Logger class can be used after the main Log class has been setup, eg in workers
inside pool/fork/thread runs

A new parent class holds all the public methods

init Logger class with "get_logger_settings" or with a dictionary Type LoggerInit that has
logger with type logging.Logger as mandatory and optional Queue entry
