-------------------------------------------------
This program is to play the game Take-Away. There are 2 players in the game and they input their
name alongside the amount of rounds they would like to play. The game then asks player one to pick
the amount of chips they would like to take from the amount of chips remaining, then cycles to player two
after that. The winner is whoever is the person to get the amount of chips left to 0 chips. There are also
statistics displayed after each round and after the game is over.

This program uses variables that are clearly named to make the code easier to understand

The game can potentially be extended by changing the value for the maximum amount of chips, adding more players, 
or more.
