syntax and require fixes; basics for person

Hi!

Your gem was broken. I fixed a few syntax and require errors. Further I added a small person class and a "me"-method to get the name and email-address of the current client...but that are just the basics for the person class.

I think your gem is a good start, but it needs more and better tests.. But it is very young, I know :-).

Best regards,
