d8e244d161 Updates NoArgs to also report invalid argument 
NoArgs currently reports "unknown command" in all cases, which
can be is a little misleading to the user if there are no
subcommands. Change it as follows

- if subcommands and one extra arg, say "unknown command"
- otherwise, say "invalid argument(s)" and show all extra args

This should produce more meaningful error messages to users, and
works for both the root and sub-commands.

f20b4e9c32 Refactor TakesArgs to use an interface for arg validation. 
Fix some typos in README and comments.
Move arg validation to after flag validation so that the help flag is run first.
Pass the same args to ValidateArgs as the Run methods receive.
Update README.
