Parse complete infos about author

[SamyPesse]

In an atom feed, author can be defined by:

<author>
    <name>...</name>
    <email>...</email>
    <uri>...</uri>
</author>

Is there a way to get these informations?

I found it, I can use:

article.element.author

But It should be good that getAuthor returns these infos.

When I created NodePie I wanted to keep it feed-format agnostic and not all formats expose additional information about the author. Today I would probably return the additional info as well but I've given up on this repo and do not want to update it, so I guess the API is going to stay as is.
