Setting up mongodb for authentication

Check the docs at: http://docs.mongodb.org/manual/tutorial/control-access-to-mongodb-with-authentication/
Short version here:
1. Start mongod (without -auth)
2. Start mongo from the cmd-line as
```
   mongo admin
```
3. Then create the admin user with
```
   db.addUser("<admin-username>", "<admin-password>")
```
4. The switch the database to swk, which is the database for the app
```
   use swk
   db.addUser("<app-username>", "<app-password>")
   exit
```
5. Shutdown mongod from the mongo console
```
   use admin
   db.shutdownServer()
```
6. Start mongod -auth
7. Edit start.sh, replace the values of MONGO_USER and MONGO_PASS with <app-username> and <app-password>

Remember that once authentication is enabled, the db can only be shutdown via:

		use admin
		db.auth("<admin-username>", "<admin-password>")
		db.shutdownServer()
