Daniel Nephin 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.

Daniel Nephin 67feb8173c Add support for setting a function to handle flag parsing errors. 
The default pflag error is to only print the bad flag. This enables an application
to include a usage message or other details about the error.
