Mentioning the purpose of this repo.

@spekary I think that this repo deserves to have a clear feature list mentioned in the Readme file (or Wiki). I recommend this because right now, we have multiple repositories for v-4. These, combined can cause confusion.

It would be good to mention the goals and intention of these libraries clearly so that they are distinguishable.

I wrote something in the readme to give this a headstart. Feel free to propose addition/modifications to it
