=====Game: Rock, Paper, Scissors=====
In this project your task is to implement a playable "Rock, Paper, Scissors" program to play against the computer.

====Rules====

  * Our game will be designed for two players.
    * You will be one player
    * The computer will be the other player
  * There are three objects which can be played: a rock, a piece of paper, and a pair of scissors.
  * The rock will break the scissors (rock beats scissors)
  * The paper will cover the rock (paper beats rock)
  * The scissors will cut the paper (scissors beats paper)
  * Gameplay will consist of three rounds
    * whoever has triumphed the majority of the time will win

====Programming Considerations====
  * You can design your program so that a certain player always goes first, or have that be picked randomly.
  * Computer's choice will be pseudo-random, using the C random number generator.
  * your program should display a welcome message and offer to print instructions.
    * This means you will need to accept input from the user on **STDIN** and properly evaluate it.
  * Throughout the program, check for invalid input.
    * Output a message and keep looping until the correct value is entered.
  * Upon the user's turn:
    * your program should prompt you for the item you wish to pick
    * You are free to come up with any sort of input scheme (1 for rock, 2 for paper, etc.).
  * Upon the computer's turn:
    * you need to print out a message indicating what piece the computer has "chosen".
  * At the end of each round:
    * display who won the round
    * explain how the round was won
  * a score needs to be kept, so at the end of the third round, you can display the winner.
  * When the game is over, ask the user if they wish to play again.
    * If yes, the game will be played again (3 rounds)
    * If no, the program should exit
