Add better example project

[makeusabrew]

Nodeflakes just isn't a good showcase for decking, but sadly the project which spawned it is private. Need to strike a balance and create an example which flexes decking's muscles a bit. Ideally would use a DB (sharded? Rethink?), Redis, web tier (load balanced would be even better), would demonstrate some good dependency stuff and some useful log tracing.

@makeusabrew https://github.com/stephenmelrose/docker-multi-container-example could be a good candidate for this as and when I get it working properly. Trying to incorporate all the different decking elements too.

Well worth adding; the example project I've got now is slightly better than the nodeflakes one (when I wrote this ticket) but no harm having more examples :)
