Physics

The top-level namespace. All of PhysicsJS is contained in
the `Physics` namespace.

It may (and should) be invoked as a function to create a world instance. For all intensive purposes, [[Physics]] and [[Physics.world]] are the same thing.

See [[new Physics.world]] for config options and function signature.

Example:

```javascript
Physics( cfg, function( world ) {
    // use world
}); // -> world
```
