/**
 * Explanation:
	The program generates random numbers between 1 and 6 for 
	both the user and the computer using Random.nextInt().
	It compares the dice rolls in each round to determine 
	the winner, and keeps count of how many rounds each 
	player wins. After 10 rounds, the program displays the 
	total number of wins for both the computer and the user 
	and declares the grand winner.
	
				Round 1
Computer rolled: 4
User rolled: 6
User wins this round.

Round 2
Computer rolled: 2
User rolled: 2
It's a tie!

...

Final Results:
Computer wins: 3
User wins: 6
The grand winner is the user.
