DEVELOP 07: RESTful Web API

[jerry914]

1. Create a copy of your monolithic web application (see class handout) ✅
2. Decide the resources (verbs + routes) your API will respond to ✅ Your API is well designed in the controller; in the future, you could also document your route design in README.md!
3. Create representers for your domain entities/values ✅
4. Update input validation and service objects ✅
5. Update controller routes to return Json representation of objects ✅
6. Write acceptance tests for your API ✅

Robocop/Smell:
A few offenses. First, try to shorten the block length. If necessary, consider using # rubocop:disable Metrics/BlockLength or # :reek:TooManyStatements to ignore the warning.
