Ideally, I wanted to convert KVector to a template class (just like 
BVector in the same file), but that would mean adjusting a lot of the 
other files. I still plan to do it in the next months though..
I would argue for both approaches: sometimes you'd want to scale down 
(when plotting hi-res sensordata on a handheld for instance) yourself, 
sometimes you really need the vector to handle values that are floats or 
more than 8 bits.. A template in that case would be our solution, I 
think (without paying for it in performance).

Yep, that makes sense.

best,
