Fixed image is empty! #5

If the ground truth mask is empty (no positive classes - which is clearly possible in real life), it shows this error.

Several measures are not well-defined in this situation, though. (Think of surface distances, for instance.) I think it's better to get an error than some magic numbers (such as "9999", for instance). Yet, it may be very useful to explicitly define corresponding outputs for all measures in this situation.
