Background

As part of adding Rust components to the CLP package, we need to document the new Rust components and our installation approach for the cargo toolchain.

Documentation Requirements

• Document the new Rust components in the CLP package
• Explain the installation approach for the cargo toolchain
  • Specifically, that cargo is installed to the user's home directory rather than clp/build/
  • Rationale for this approach (per-user installation, default path, avoiding version conflicts)
