+/* Part 1 : 
+Create a basic version of Scissors Paper Stone where the user inputs one of "scissors", "paper", or "stone", the program internally randomly chooses scissors, paper, or stone, and the program outputs whether the user won, the program won, or it's a draw.
+Rules: scissors beats paper, paper beats stone, and stone beats scissors. If both parties choose the same object, it's a draw.
+
+Part 2: 
+- win-loss record : Output this win-loss record in a format you like in the program output. You can also output the number of draws and/or each party's winning percentage if you'd like.
+- Username : add a feature to collect the user's name as the first input after the page loads
+- Formatting : use <br> to create new lines in the output */
