Add example project using ecs.

It will probably be with Panda3D.

I put the results of my toying around with ecs up here. It's pretty simple, not yet done and probably not optimal as I'm still learning about entity component systems, but I hope it's enough for a momentary example.

This looks awesome! I don't have time to look at it in detail right now (see #8), but I'll be looking at it soon. I like that it's in pygame as it is more well-known throughout the Python community and arguably easier to set up than Panda3D. Hopefully we can have an example project in both pygame and Panda3D.

I can provide a sample project using PySDL2 as well, if there is interest. Something simple, with a main loop and a few systems (rendering and movement) so that you can see a window and move a sprite around.

While an example project is certainly helpful, what I would have need is a simple example, that showed, how the different classes of the ecs package are instantiated and connected together.

Something like this: https://gist.github.com/SpotlightKid/ee3be28e6884945401cd
