GuessingGame

//Jasmine Kennedy
//TA: Isabel Atkinson
//this program asks the user to guess a random number, and continues asking what number it is until
//guessing correctly. After guessing correctly the user can choose to play again or not.
//if they do not want to play again statistics about their play time is released (best game, num games, etc)
