Cpp2Rust: Translates C++ to safe Rust automatically

Cpp2Rust is an automatic translator that converts C++ code to fully safe Rust using a syntax-driven approach based on clang's Abstract Syntax Tree. The tool parses C++ files, traverses the AST, and generates Rust code with a runtime library (libcc2rs) that handles C pointer semantics through a Ptr type, ensuring safety compliance with Rust's borrow checker. By default it produces fully safe Rust using a reference counting model, though an unsafe Rust generator is also available for performance comparisons.
