+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.
