Yes, you have to. The macros YADE_... are declarations and 
initializations. The difference between registered and non-registered 
data will correspond to different type of variables in the macro. A good 
example of the different situations is pasted below.

You made a small mistake probably.

Yes again. YADE_... contains the declaration and definition of the 
constructor. You have to remove it from the hpp and cpp when the macro 
is in place.
