CLI generate doc command

[WilliamRagstad]

Many programming language CLI tools have extensive functionality beyond just compiling and running code.
One feature that we want to implement in RustScript's CLI tool rsc is automatic HTLM documentation generation from code comments. This is thought to be written similar to Java doc comments, TypeDoc or TSDoc and have similar command line interface as Rust's cargo doc/rustdoc.
