Changed the returned json object and how front end utilizes the new object format

Since you're building a more complicated json string here, let's not do it by hand. Instead create a HashMap and then use the Gson library to conver it to json.

For example:
<pre>
        HashMap fooMap = new HashMap();
        HashMap criteriaMap = new HashMap();
        criteriaMap.put("communication", 5);
        criteriaMap.put("teamwork", 7);
        fooMap.put("id", 12345);
        fooMap.put("assessmentCriteria", criteriaMap);
        Gson gson = new Gson();
        System.out.println(gson.toJson(fooMap));
</pre>
