Blackjack: Implements Panda, Tiger & Eagle Levels

[rastreus]

I tested to see if I achieved the desired results by "playing" the game using irb.
I was able to change a few of the specs to actually unit test for the Panda Level, but I wasn't sure the best ways to test for the Tiger and Eagle Levels.
It's alright, but I know that there's a more elegant, idiomatic "Ruby Way" to accomplish the same results.
I definitely feel this way for the Eagle Level. I feel like adding conditional statements into #status wasn't the best way to get it done. But it worked. Anyway, if there are any hints or what you would do differently then I would love to hear it.
Thanks.

You should write this method as

def bust?
  value > 21
end

The reason --- if you're doing an "if" that returns true/false, your condition is already what you want

Ah! Thanks for pointing this out. There's no reason for the if. Exactly.

I left some idiomatic comments on the "ruby way" to organize and name your code.

Overall though, your code was very good, and your tests look nice.

@jwo I made some of the changes that you suggested and just wanted to see what you thought. I don't want to dwell on the first assignment too long, but I wanted to get it to a good level before moving on to the next episode.

Looks as good as I've seen for the blackjack Eagle.

If you ever get interested in some advanced topics, we can revisit this. Right now, we have a lot of presentation logic in the Hand class, like hiding or showing the cards depending on the game state. Instead, it'd be kind of cool to have a DealerHandRenderer and a PlayerRenderer and have those do all the rendering.

For now though, looks great!
