Support for interfaces with default methods

[rolve]

I think Java 8 default methods would be a great way to convert or enrich parsed arguments. For example, I tried the following to convert a String to a Path:

public interface Args {
    @Option(shortName = "d")
    String directory();

    default Path directoryPath() {
        return FileSystems.getDefault().getPath(directory());
    }
}

Unfortunately, jewelcli does not seem to support default methods. When calling directoryPath(), I get null.

Without having looked at the code, I feel like this should be easy to implement. All that needs to be done it to not override/implement default methods in proxies.

Interesting idea. At the moment we don't have any java8 support. I will
take a closer look at what is going on in your example.
