Episode 1: Panda-Eagle levels

I modified the Game api to restrict access to the dealer_hand and player_hand attributes in the Eagle level. I did not want to allow access to those attributes from outside the class - not sure if that is a good design decision or not. 

In the Tiger level I struggled with the best way to structure the test (line 236) - I attempted a mock but couldn't get it to work for me. 

I'd love some feedback on my code and if there would have been a better way to approach things.

Thanks!
