# We create a standard logger with two handlers
# One of them is using io.StringIO for streaming
# Subsequently we add the value() method to the logger, e.g. it will be possible to call
# logger.value() and get the entire history of all messages sent to the logger.
#
# I have never managed to get my head around logging in Python. Any comments are very appreciated.
