* This function kind of breaks the hands off approach of the rest of the class. In here

* to the UDS standard than the rest of the code where the code doesn't really know anything
* about what it is doing - it just reads arrays and such.
* No, in here we end up with hard coded handlers to figure out each type of message and how to
* interpret it to a fine level of detail. Look away code purists, this is likely to be a mess.
* The output here is potentially multi-line and is useful for debugging a UDS problem. You'll
* get a finely detailed dump of exactly what the message means.
