GamePhysics contains a "standard library" of Vector-related code that should be moved elsewhere and imported back into each case study that uses vectors

    I don't quite understand why these are here. They all look like they should be explained somewhere outside of GamePhysics and imported here. Since they're all related to functionality of Vectors, they might really be part of a "standard library" that should be built for each example using vectors in any of its expressions.

As suggested by the title, GamePhysics contains a "standard library" of Vector-related code that should be handled elsewhere and pushed into each case study as needed.
