Contracts should be defined by interface rather than abstract classes

The ReadModel component is affected as well.

There are cases where we use abstract classes to define contracts on our internal projects. For this open source project we see that adding some flexibility by using interfaces is probably better.

So +1 for refactoring the contracts towards interfaces. We'll try to do it ourselves in the upcoming time, but a pull request would be very welcome!

I'm going to take this unless someone else has started.

We haven't started yet, so go for it :)

On a sidenote (we still need to update the README's), on freenode we have #qandidate where we can discuss stuff when slow-chatting on github doesn't work :)
