Dear Developers,

I checked out a MASK while classifying with i.smap. The MASK contains NULL data
cells where I wanted to mask out areas. 
It's interesting i.smap uses the MASK on the one hand but fills up the MASK 
with the MASK-sourrounding classes on the other hand. Obviously it doesn't read
the MASK as an area where there should be no classification but uses the neighbourhood
relations to fill up the MASK though.

Usually it should do it without calculating on the masked out areas?
