This function works as a decoding/encoding dispatcher between Django's '''HttpRequest'''-object and 
arbitrary defined method-functions of the json-rpc service. Those method-functions shall return a 
dictionary-object such as '''{'result': <result_data>, 'error': <error_data>}''' . This dispatcher-function 
is suitable for non-public json-rpc apps handling specific data process/validate tasks.
