modularization convention discussion

[cyan33]

Along the way I'm working around with javascript packages, I noticed that it looks like the best practice is using closures instead of Class when handling modularization.

So in our game framework, I also took this approach, in which case, most of the game components like canvasUtils, drag n drop, AI, should export something like createXX(). But for some of the base class like Sprite and Particle, the intuitive way is to use class. So I think I should just mix them up.

But like you can see, everything inside the src/component folder uses class, while other modules outside uses closure.

Just to clarify things up.
