Subject: [PATCH] Finalized license, warranty flags
MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

Made the clap Parser able to be run without a subcommand, by wrapping
the subcommand field of the Parser struct in an Option<Command>.

Further destructured the subcommand arms fields in main with Some(),
and made the default case None just return ().
