+* @brief Decode the payload of an OBD-II PID.
+*
+* This function matches the type signature for a DiagnosticResponseDecoder, so
+* it can be used as the decoder for a DiagnosticRequest. It returns the decoded
+* value of the PID, using the standard formulas (see
+* http://en.wikipedia.org/wiki/OBD-II_PIDs#Mode_01).
+*
+* @param[in] response - the received DiagnosticResponse (the data is in response.payload,
+* a byte array). This is most often used when the byte order is
+* signiticant, i.e. with many OBD-II PID formulas.
+* @param[in] parsed_payload - the entire payload of the response parsed as an int.
