card game elaboration

Introduction: the rule of this game is similar to the previous one, but this one added a new rule--if two players are tied, they need to pick another card from their hand to battle!

Self-evaluation: the change I made was changing the rule of "tie" to break the situations of ties so that the game won't be boring if the tie keeps happening. When coding this part, it was pretty easy because all I needed to do was to change the structure of the "compare" function, so things were going well. I also re-designed the cards and the card back. Right now, there are three colors and all three patterns on the card back so that players can get familiar with them.
