yaml omitempty

[Érky Lima]

I was using this library, but we have a problem and i can try to fix it, Anyone more have the problem that can't omit empty data? It's a great function that will improve this library a lot.

It's a yaml generated with this library, but i wish omit the empty fields to reduce the file size. What do you think about that?

Could you please provide a sample code for generating a shorter version of the output in this comment?
