* added time counting stub
* added score counting stub
* added win check stub
* made it so you pass gameMap to the logic
* you pass the list of players too

*
out of minor -
* made add_player_mark() also call the player instance to record mark into it's internal list
* put the exception message into a separate variable for the sake of simpler representation
