1. bug fix players leaving the table: elif -> if
2. rename: flipACoin() -> tossACoin()
3. some comments and placeholder messages got better.
Updated card values (in the Enum) to make them more readable.
added init and messenger module. Big things coming soon.
All messages, formerly print("*** ..."), are now gone.
We use our new messenger.py module to typeout messages into logfiles or into sys.stdout.
This has several advantages. We can have some randomization in the wording of each message. We can easily control, which messages are to be typed only if vebose option is on.
Dealer now deals cards to players and collects them after the hand is over.
Major overhaul: Dealer becoming the centre of the universe. He incorporates the deck, game, table, setOfPlayers. (makes more sense that way, at least for now...) (-:
Players now decide randomly whether they want to join or leave.
A game of poker can last 100-200 hands, depending on the players' random decisions.
Added first shuffle method: cut
Improved card transfer between dealer and players. (Intermediate stage where the card was copied is gone now.)
- Added RealRandom with shuffel and random n umbers from random.org wit a standart random fallback
- added prints for the cards
