Fixes #11

Expected Behavior

go to http://127.0.0.1:8080/api/v1/customers and it should list all customers go to http://127.0.0.1:8080/api/v1/customers/0 to see the first customer -- test other id numbers to see singular customers go to http://127.0.0.1:8080/api/v1/customers?active=false to see just the customers that dont have any past orders

Steps to Test Solution

1. run npm start if you've already got the full database generated
2. comment out routes other than /customers
3. add app.use('/api/v1/', routes); after routes declaration in app.js
4. Go to the 3 urls listed above and see if they give the results
