Ok, thanks for rewriting :)

I was thinking about this, but it's done only once at startup anyways and if we 
replace it with a map construction, we will just trade this nested loop for:
 1) creating a map (still having the temporary vector)
 2) inserting into map, i.e. allocating space for flags, making copies and 
looking for the right spot with O(N*logN)
 3) looking them up in map, yet another N*logN.
It's probably not worth doing so unless we have several hundreds of flags. 
Still want me to change it?
