//--ApiResponse<PageData<T>>
//--ApiResponse<T>
//--ApiResponse<T> where T is simple type such as object, string, int, etc.

//implementation notes
//-get the actual T
//--when T is DataObject, add into a queue (i.e. a FIFO Stack) for next step processing
//-loop until queue is empty
//--process (add model details) for the first item in queue, remove it after processed
//--during the processing, if found any property is type of DataObject, add the nested type into queue
//-the reason to use a while loop with a queue is to avoid using recursive implementation which will throw a stack-overflow exception when it's too many nested types
