Dbconfig

Set up basic db config to persist data to a remote mongo host.
In the config for the API server/host, need to set the following environment vars (the values for which I'll pass to you more privately):
    host: process.env.MONGO_HOST,
    port: process.env.MONGO_PORT,
    user: process.env.MONGO_USER,
    password: process.env.MONGO_PASS,
    database: process.env.MONGO_DB

Then should be good to go!
