wuttjamaican.cmd
deprecate `wuttjamaican.commands`
Subcommand.make_arg_parser()
split that out for clarity
`wutta setup` is the only real sub/command yet, and it does nothing
this has 100% test coverage and i intend to keep it that way. api docs have a good start but still need narrative. several more things must be added before i can seriously consider incorporating into rattail but this seemed a good save point
