Dear Gamer, this is Y.A.N.G, the yet another number game!
		Your task is to crack a five digit code, digits 0-9, all unique.
		Valid examples: 01234, 75609, 90437, etc.
		Not valid examples: 11345 (1 is repeated), 123456 (6 digits), 1234 (4 digits)
		Yang creates a new secret code each day at midnight.
		A gamer name is required!
		You have 6 tries to crack the code. Not enforced by server, there is an enforce6 flag thought.
		There is an practise mode to play a new game at any time.
		There is an echo api endpoint to test your requests

		
		This is the API:

		GET-Requests:
		/help -> produces this text. (output-format: text)
		/ping -> shows server and data base vitals (output-format: json)
		/api/my-current-game -> returns data from last unfinished game (output-format: json)

		POST-Requests:
		0. /api/echo -> returns the request authorization header and the body - for testing purposes
		
		1. /api/daily-game -> play the daily game, a correct authorization header and body required.
		2. /api/practice-game -> play a practice game, a correct authorization header and body required.
		
		
		
		
		Details for 1. and 2. 
		header: Authorization: <your name>
		
		start a new game:
		body: {
			"gameid": "new", (magic string to start a new game)
			"try": "12345", (the first try to crack the code) 
			"enforce6": true (optional, if true the backend will only 
								accept 6 tries for this gameid )	
		}
		continue the game:
		header: Authorization: <your name>
		body: {
			"gameid": "01G4KYESPM1S4EXB5X9GZ2MVMWM9AG", (the id returned from first request)
			"try": "34567", (the next try to crack the code) 
		}

		returned data example:
		{
			"gameid": "01G4KYESPM1S4EXB5X9GZ2MVMWM9AG", 
			"hit": false, (true, if game was won)
			"response": "y-gg-", (green: position 3 and 4 are correct, yellow: digit is at wrong position)
			"sequence": 3, (your third try)
			"time": "2022-06-04T16:48:39.99019074+02:00",
			"try": "74238",
			"type": "practice" (a practice game, not the "official" daily game)
		}

		Have fun!
