README should describe the purpose and features of ANUBIS

Hi pshep!

I would've just sent you an email but I couldn't find your address so I thought I may as well create a ticket for a prob I've spotted before I've even tried ANUBIS and that is that the README only describes how to configure ANUBIS. Before it covers that, it needs to describe what ANUBIS is and summarize its main features so that people know if it can do what they want or not.

In my case, I'm running a Debian/cgminer mining rig with a number of Icarus block erupters attached. The problem is that every couple of days I'll log in and discover they're all ZOMBIEfied and so I have to manually restart cgminer to get them going again. If I was to install ANUBIS, would that monitor cgminer and auto-restart cgminer/ the mines so that I need not do it manually?

Thanks!
