public class Test
{
    @Tag(value = 1)
    public int num;
}

questions is how can i serialize this obj to the protobuf format using zigzag 
encoding? thanks!

Perhaps a @Tag(value = 1, signed = true) could give a hint to 
protostuff-runtime (not yet implemented) which would call output.writeSInt32 
instead.
