Wrap RapidJSON to be used as objects of predefined class

Objects are represented as DTOs with json serialization/deserialization support:

    

    class UserDto : public JsonObject {

      public:

    	JsonValue Name;

    	JsonCommonValue Role;

    

    	UserDto(char *name = {}, TUserRole role = {})

    		: Name(this, "name", name), 

    		  Role(this, "role", role){};

    };

    

    class GoodsDto : public JsonObject {

      public:

    	JsonValue Id;

    	JsonValue Created;

    	JsonValue Group;

    	JsonValue Name;

    	JsonValue Price;

    	JsonValue Quantity;

    	JsonCommonValue Deleted;

    	JsonCommonValue StoreName;

    

    	GoodsDto(int id = {}, uint32_t created = {}, char *group = {}, char *name = {}, float price = {}, double quantity = {}, bool deleted = {}, char *storeName = {})

    		: Id(this, "Id", id),					

    		  Created(this, "Created", created),	

    		  Group(this, "Group", group),			

    		  Name(this, "Name", name),				

    		  Price(this, "Price", price),			

    		  Quantity(this, "Quantity", quantity), 

    		  Deleted(this, "Deleted", deleted),	

    		  StoreName(this, "StoreName", storeName){};

    };

        

	class GoodsList : public JsonObjectsArray {

	public:

		bool Validate(JsonObject *item) override { return item->Validate(); }

		JsonObject *CreateItem() override { return new GoodsDto(); }

	};

    

    class OrderDto : public JsonObject {

      public:

    	JsonValue Supplier;

    	JsonCommonValue DateTime;

    	JsonValue Goods;

    	JsonValue User;

    	GoodsList goodsList;

    	UserDto userDto;

    

    	OrderDto(char *supplier = {}, uint32_t dateTime = {}, char *userName = {}, TUserRole userRole = {})

    		: Supplier(this, "supplier", supplier), 

    		  DateTime(this, "dateTime", dateTime), 

    		  Goods(this, "goods", &goodsList),		

    		  userDto(userName, userRole),			

    		  User(this, "user", &userDto){};

    };

sample code (from tests):

    		OrderDto order;

    

    		CHECK(order.TryStringParse("{\"supplier\":\"Dell\",\"dateTime\":1657058000,\"goods\":[{\"Id\":1,\"Created\":1657052789,\"Group\":\"Keyboards\",\"Name\":\"K1-100\",\"Price\":58."

    							 "\"Price\":358.25,\"Quantity\":648.2,\"Deleted\":false,\"StoreName\":\"\"}],\"user\":{\"name\":\"Joe Doe\",\"role\":1}}"));

    		CHECK_EQUAL(order.goodsList.Size(), 3);

    		CHECK_EQUAL(order.goodsList.Item(0)->Created.Value, 1657052789);

    		STRCMP_EQUAL(order.goodsList.Item(2)->Name.Value, "K4-100");

    		STRCMP_EQUAL(order.userDto.Name.Value, "Joe Doe");

    	}

    	orderDto.goodsList.Add(new GoodsDto(3, 1657054789, "Keyboards", "K3-100", 258.25, 548.2));

    	orderDto.goodsList.Add(new GoodsDto(4, 1657055789, "Keyboards", "K4-100", 358.25, 648.2));

    	const char *jsonStr = buffer.GetString();

    	STRCMP_EQUAL(jsonStr, "{\"supplier\":\"Dell\",\"dateTime\":1657058000,\"goods\":[{\"Id\":1,\"Created\":1657052789,\"Group\":\"Keyboards\",\"Name\":\"K1-100\",\"Price\":58."
