A simple utility to obtain the absolute path to your project root.

match project_root::get_project_root() {
    Ok(p) => println!("Current project root is {:?}", p),
    Err(e) => println!("Error obtaining project root {:?}", e)
};

I was trying to slurp in some config files during a test but the directory location was not what I expected - and indeed would not be the final location of that directory on a deployment.

I couldn't find an immediately obvious way of finding out my position relative to the project root so built this little helper.
