ComputerPlayer.java

/*The ComputerPlayer class is basically just the same as the Player class
with minimal difference(as in). I couldve just make it inherit from the player
class para ioverride nalang nako ang setNumber method since ag implementation
rjud ana maoy different, pero nagpaSingletonSingleton man lage ko. type nuon kog
balikbalik. Inheriting from class that follows the Singleton design is not good 
practice and by inheriting so, it breaks the rule of Signleton design, if I want to
make this class inherit from player, then might as well remove the Singlton design.
