Promises / backend db

[mjg17]

Hi all

I've pushed my clean code and instrumented code to github, here:

https://github.com/mjg17/organisations-database/tree/server-store-api
https://github.com/mjg17/organisations-database/tree/server-store-instrumented-promises

See backend/stores/ and test/backend/

If you'd like to try it, clone my repo and check out the server-store-instrumented-promises branch.
Then run:
npm install
npm run test

One thing I forgot to mention: Promises are included in ES6 so no external module is needed for them.

Cheers
Michael
