Refactors camera and prediction engine traits.

Browse Source 
Moves camera and prediction engine implementations into traits for each engine,
decoupling the engine-specific logic from the core classes, promoting code reuse
and maintainability. This change allows for easier addition of new engines and
customization of existing ones.
