Big-Ugly Style Update (#278)
* Bulk replaced tabs with spaces * Bulk removed trailing whitespace from lines * Replaced c-style comments with c++-style comments in file banners * Replace nested namespace definitions with single concise definitions (C++17), this keeps the indentation more manageable * Cleanup ordering and spacing of include directives * Bulk renaming of header file extensions from '.h' to '.hpp'. * Update CODING-STYLE.md * Update target_compile_features from cxx_std_11 to cxx_std_20. * Refresh .clang-format file. Still needs a lot of tweaking.
