Feature request: abscissa new generates subcommands under existing commands

[cbrit]

It would be really great if abscissa gen allowed you to add subcommands underneath existing commands. For example, say I have a abscissa cli cli with command cmd,

// in cli project root
abscissa gen cmd --subcommands=[subcmd1, subcmd2, subcmd3]

would result in code generated

src/
    // snip
    commands/
        cmd/
             subcmd1.rs
             subcmd2.rs
             subcmd3.rs
        cmd.rs
    commands.rs
    // snip

Implicitly this shouldn't overwrite cmd.rs if it already exists.

Although there's no command to generate subcommands in Abscissa, you can create subcommands and nested subcommands manually in your project.
