[Ovmsdev] Vehicle Support Checklist

[Mark Webb-Johnson]

I've updated the development document with some vehicle module development checklists. You can use these checklists to know what vehicle parameters the OVMS system supports, and how you can map a specific vehicle to these.

The Tesla Roadster supports 100% of these (obviously). It would be good to use these ongoing for other vehicles, both as a target list to get to 100% support, and as a worksheet for both CAN bus information and progress.

I hope you find them useful.

Regards, Mark.
