Pockets.cs

// script to handle the table's pocket collisions for resets / destruction.
// predicted objects sometimes have their rigidbodies moved out of them.
// which is why we handle collisions in the table itself, not per-object.
// because here we can check who the rigidbody belongs to more easily.
// ... that's just the best practice at the moment, maybe we can make this
//     easier in the future ...
