[Ovmsdev] GPS Logs (TWIZY) -- Future Feature?

Nikki, Mark,

I decided against adding the current power to the GPS log because that's 
something not defined in the general virtual car model, all other cars 
lack this feature, and I wanted to make the GPS log function fit for 
inclusion in the framework first.

I currently send the power usage log (RT-PWR-UsageStats) once per 
minute. You can correlate that to the GPS log to get the power usage of 
minute long sections, but that's a lot of manual work and not very 
detailed (e.g. for hills).

Btw: using the power collection feature, you can also measure certain 
route parts: easiest way is to turn the Twizy on just before driving the 
section, then turn the Twizy off and check the power stats message. But 
a combined GPS track would of course be far better and more accurate.

Mark, you mentioned a "kWh used" value with the driving log function, so 
I guess we can think about adding the power usage to the standard car model?

But I'm not sure yet if the way I currently collect power usages is 
suitable and sufficient as a standard. As I wrote in the docs, that's 
work in progress... any thoughts on this?
