      The `teletype add` will create a new command and place it into
      appropriate structure in the cli app.

      Example:
        teletype add config --desc 'Set and get configuration options'

        This generates a command in app/commands/config.rb

      You can also add subcommands

      Example:
        teletype add config server

        This generates a command in app/commands/config/server.rb

      The 'teletype new' command creates a new command line application

      The PROJECT_NAME will be the name for the directory that includes all the
      files and be the default binary name.
