CodeReview of #148: Processing of imported supreme court judgments - process part

consider using Gson (https://sites.google.com/site/gson) to simplified writing test using json. We can create GsonWrapper
```
public class GsonWrapper {

    private Gson gson = new Gson();


    public JsonObject asJsonObject(String text){
        return gson.fromJson(text, JsonElement.class).getAsJsonObject();
    }

    public String normalize(String text){
        return asJsonObject(text).toString();
    }

}
```
then
instead of writing:
```
String text = "{\"bre\":\"sss\", \"arr\":[\"1112\", \"abc\"]}";
```
we can use
```
String text = gsonWrapper.normalize("{bre : sss, arr : [1112, abc]}");
```
