Hi George,

     - I don't see where the variable mem_baseline is initialized before 
you invoke the method baseline()?  I am not
       overly familiar with NMT but it looks like your might need to do 
something like: MemBaseline& baseline = MemTracker::get_baseline();

     - Your indentation for your edits at least in the webrev looks very
