Popover - About?

[mrmonteith]

I was looking through the documentation on the different features. One of them had an About section. I find that helpful. I had never heard of Popover, since I've never worked with IOS directly. I'm thinking every page should have one. For those the concept is new. Of course I searched to find the answer. I'm just thinking it's a nice to have for anyone not to assume. BTW, great work.
