* General 2D Reduction Kernel * Move the reduction kernel from the example * Split the code and add the necessary policy, problem, shape files as per ck_tile convention * Add/modify the headers * Modified the example to work with the 'new' kernel * Added tests for the kernel * N-D refernce reduce * Added support for N-D input with transform to 2D * Added padding to support various input sized tensors * Bug fix in the thread buffer constructor * Some comments to explain the reduce2d block kernel * comments resolution * clang-format * comments resolution * clang-format * clang-format * comments resolution * clang-format
