rhg: add a limited `rhg root` subcommand

Clap has been choosen for argument parsing for the following reasons:

- it's a wildly used and maintained crate
- it can deal with OS encoding making it suitable for any encoding
- it supports nonambiguous prefix matching as already available in hg
- it will soon allow for structopts-style declarative pattern instead of the
  currently used builder pattern

pub mod root;
use crate::error::CommandError;

/// The common trait for rhg commands

/// Normalize the interface of the commands provided by rhg
pub trait Command {
    fn run(&self) -> Result<(), CommandError>;
