A new package named 'manifest' is introduced in this commit. It comprises a single structure and related functions for managing manifests. Additionally, 'command_init' has been altered to use this new module instead of using its previously hard-coded functionality. A reference to 'manifest' has also been added in the Cargo.lock and command_init/Cargo.toml files.
This commit creates a new Rust workspace which includes two packages: "command_init" and "mccli". The command line argument parsing for these packages is powered by the "clap" dependency. An automatically generated Cargo.lock file tracks all dependencies. Additionally, a .gitignore file was configured to prevent tracking of unnecessary build artifacts and IDE-specific files.
