C# Class Project2.PhysicsSystem

This class encapsulates the physics system for a given world of physics bodies. A physics body is a (usually) non-drawn, relatively simple shape or mesh that contains properties (mass, inertia, etc) that the physics engine uses to resolve collisions and solve kinematics for. A physics body may be dynamic or static. A static body's position cannot be changed by the physics engine, but needs to be moved externally. A dynamic object's position will be affected by gravity and other forces and collisions, and does not get moved manually. Its position and orientation are queried externally and used to render representative objects/models on screen (usually more detailed than the physics mesh). This class is implemented as a GameSystem, meaning that once it is registered, it is automagically updated at the correct frequency.
