Parse command-line arguments into Self.

The primary one-stop-shop trait used to create an instance of a clap [Command], conduct the parsing, and turn the resulting [ArgMatches] back into concrete instance of the user struct.

This trait is primarily a convenience on top of [FromArgMatches] + [CommandFactory] which uses those two underlying traits to build the two fundamental functions parse which uses the std::env::args_os iterator, and parse_from which allows the consumer to supply the iterator (along with fallible options for each).

See also [Subcommand] and [Args].
