Contributions summary:Raymond's commits primarily involve refactoring and modifying the `Rotation` class and associated files within the Apache Commons Math library. They are focused on replacing and renaming classes to improve consistency, updating Javadoc references, and adapting the codebase to use `Cartesian3D` and `Cartesian2D` classes. The changes include modifications to constructors, methods, and documentation related to vector operations and coordinate systems. This work indicates a strong understanding of the mathematical concepts and codebase structure of the library.
