I have friend who is going to walk the Camino de Santiago
        
        my Spring Boot Project follows the MVC design pattern
        
        
        Model-View-Controller
        
        the Model (holding the data) will be my RestService
            the Model has methods the "front-end" code will call 
            to access the data (RouteService class)
            
        the Controller (the code to respond to a User request)
           will be the @RestController, this code will
           include the Mapping of the URL to to methods with
           will in turn call the Model (RouteRestService class)
           this is a WebService EndPoint
           
        the View (presents the data to the User) is genered by
           Spring as JSON (produces="application/json")
           
           JSON basics:
           { } => JSON Object
           name: value => a field, the value can be a JSON Object, or text or an Array
           [ ] => JSON Array
