Jacopo Cappellato updated CLI-179:
----------------------------------
    Attachment: CLI-179.patch

This is my attempt to implement "standalone" options for the new Option.builder() and DefaultParser.
It would be great if someone with more knowledge of the CLI codebase than me could review it, possibly test and let me know if this is the right approach. The JavaDoc comments should be enhanced too.

> it is currently impossible to have options like "help" or "version" if we also have some required options. The parsing results in an error "Missing parameters".
> But for an "help" or "version" option, it would be usefull to display the wanted information, even if required options are not set.
