Examples

let options = vec![
    Opt::new(
        "username",
        Some("u"),
        Some("user"),
        Some("NEREON_USER"),
        0,
        Some("admin"),
        None,
        Some("User name"),
    ),
];
let args = "-u root".split(" ").map(|a| a.to_owned()).collect::<Vec<_>>();
assert_eq!(nereon_init(options, args), Ok(json!({"username" : "root"})));
