/// <summary>
/// This class helps you to synchronize the velocities of a physics RigidBody.
/// Note that only the velocities are synchronized and because Unitys physics
/// engine is not deterministic (ie. the results aren't always the same on all
/// computers) - the actual positions of the objects may go out of sync. If you
/// want to have the position of this object the same on all clients, you should
/// also add a PhotonTransformView to synchronize the position.
/// Simply add the component to your GameObject and make sure that
/// the PhotonRigidbodyView is added to the list of observed components
/// </summary>
