All the results I got for GCC(Group Closeness Centralisation) are negative numbers, not in the GCC range: 0 < GCC < 1.

The bug was in createDistanceMatrix() method, in line 1210. We needed to call minmax with std CC not plain CC:

minmax( (*it)->SCC(), (*it), maxCC, minCC, maxNodeCC, minNodeCC) ;

Fix commited

Version 0.81: wrong closeness centrality (CC') and group closeness centrality (GCC);
The GCC now are positive numbers, but still out of the range of 0<GCC<1; and also the CC' out of range of 0<CC'<1.
