* The purpose of this program is to allow a user to play a game of rock, paper, scissors
* by entering in a number between 0 and 2, where 0 means picking scissors, 1, means picking rock
* and picking 2 paper. Furthmore, the program should pick a random value for the computer which is
* currently called Player 2 in case. Lastly, the program should display a message saying which player
* one or display a message saying it's a draw or that the user entered in an invalid number.
