File summary:
    The purpose of this file is to handle the responses coming from the server. The responses first reach the client file
    and control is passed to this response_handler file. The ResponseHandler class has the runResponseCodeAction function
    which calls the required function based on the response code received from the server.

    Almost all of the functions defined in this class just involves printing the payload that has been returned back
    from the server
