- Updated the math module to include vector and matrix operations, noise generation, Bezier curves, and random number utilities. - Introduced the tensor module, providing TensorFlow 2-style eager execution and graph building capabilities. - Enhanced documentation to reflect the new features in the math and tensor modules, including usage examples and API references. - Modified CMakeLists.txt to include the new math and tensor modules, ensuring proper build configurations.
