This is a set of zero or more PhysicsObjects.
It's handy for returning from functions that need to return multiple PhysicsObjects.

void PhysicsObjectCollection::add_physics_object | ( | PT(PhysicsObject) | physics_object | ) |
Adds a new PhysicsObject to the collection.

void PhysicsObjectCollection::add_physics_objects_from | ( | const PhysicsObjectCollection & | other | ) |
Adds all the PhysicsObjects indicated in the other collection to this collection.
The other physics_objects are simply appended to the end of the physics_objects in this list; duplicates are not automatically removed.
