* Cleans the namespaces to include only what is needed.
* Converts List<> to arrays
* Fixes bug in bridgetest
* Fixes bug in raycasttest
* Reintroduced const keyword on constants like in Box2D
Nice finds, those tests now work how they are supposed to. The const keyword is good too, not sure why we didn't keep it there to begin with.
The List<> to array should be good, but probably won't make a huge perf difference. List<T> is highly optimized and the way we use it there isn't much difference other than a small amount of working set overhead compared to array. Either way, we might as well be as bare-bones as possible in the contact solver since it is the hot path.
