HateosResourceMappingRouterHttpHandler should output hyperlinks for resource

HateosResourceMappingRouterHttpHandler

• Currently the response is only JSON.
• Actual possible links are no where in the response (maybe should be in headers??? or introduce an envelope ).

{
   type: type/class-name-here
   value: JSON
   links: [
      {
         method: GET
         url: https://example.com/resource-name/{id}
         relation: SELF
      }
   ]
}

• 
  From there, an API could be considered more “mature” as a REST API as it adopted the following ideas:
  
  Level 1: Resources (e.g. a resource-aware URL layout, contrasted with an opaque URL layout as in XML-RPC)
  Level 2: HTTP Verbs (using GET, POST, DELETE, etc. properly)
  Level 3: Hypermedia Controls (e.g. links)

Level 3 is where the uniform interface comes in, which is why this level is considered the most mature and truly “The Glory of REST”
