Add an "About" section to the readme

[cullylarson]

It would be helpful to have some documentation of what the library is and why the library should be used, near the top of the readme (i.e. a sort of justification for the library's existence). Also, perhaps, an explanation of when not to use the library. There is some information like this scattered throughout the readme, but you have to read the whole thing to find it.

For example, I found these snippets really helpful, but they're all the way at the bottom of the doc:

The main purpose of this library is to make sure actions are consistently dispatched on all pages on client and on server from getInitialProps function...

If you need a static website you don't need this lib at all because you can always dispatch at client side on componentDidMount just like you normally would with bare React Redux, and let server only serve initial/static markup.

PR is welcome.

@kirill-konshin I'd definitely be willing to do a PR. I just don't feel like I understand the library well enough to explain it.

To clarify my motivation for suggesting the additions to the readme, when I first came across the repo, I didn't really understand what it was. I was looking for something that would make Redux work with Next. I couldn't be sure next-redux-wrapper did that because there wasn't an explanation of what next-redux-wrapper is.

Maybe I can suggest something in the next week...

@cullylarson Something like that?
