What just happened?

With the test samples, you can visualize most features in Cocos2d-x, what they do, as well as see some of the ways you can initialize and customize them.

I will refer to the code found in the tests quite often. As usual with programming, there is always a different way to accomplish the same task, so sometimes, after showing you one way, I'll refer to a different one that you can find (and by then easily understand) inside the Test classes.
