Built in Physics System

[scottbigbrain]

I suggest that work should be started on making a built in physics system.
There are several bindings for things like chipmunk that could be used, but I propose that we could build one for GameZero. I have found the beginnings of a Julia Physics System called Matter.jl that could be used to do this.

Integration with Matter.jl will be a good idea.

I really like this idea. Would this be a new dependency for GameZero or should we ingest the code and make it built-in?
Personally, I'm leaning towards importing it as a dependency.

Matter.jl isn't fully functioning yet, so building the code in might be a good way to go so that we can shape it to the needs of GameZero.jl. On the other hand, having it built in would make GameZero.jl a larger package.

I think what would work really well is to have built in support for Matter.jl so that if the person did not have Matter.jl then GameZero.jl would ignore physics stuff, but if the user had Matter.jl then it would automatically make a world and engine and simplify the creation and rendering of physics objects.

Either way, if we use Matter.jl then we would have to finish building the physics system.

To begin with, it would be good to get some example games built with Matter.jl with the existing actor system. That will hopefully give us some ideas on what a good API for this should be inside GameZero.

Okay, just remember that the only part of Matter.jl that is currently functional is the vector.jl and vertex.jl, the others are still in development.
