Hi Pete,

I agree with the renaming. It is more generic that way.

I would be inclined to specify the NXpositioner a bit more like adding 
limits, units. What do you and Stuart (the current proposer of NXmotor) 
and the rest think ?

Currently the spec converter we have written converts a spec motor to a 
single NXdata value but I don't find this very good because we have lost 
the information that it is a positioner.
