Added default value for GetTriads1 SampleNodes as it was missing a default value.
Removed GetNodeTriads function that was GetNodeTriads2 as it was redundant of GetNodeTriads3. Changed comment for GetNodeTriads3 to 2 due to removal.
Changed typename PGraph::TNodeI to PGraph::TObj::TNodeI for correct object also missing Graph->GetNI in for loop when getting MidNI.
GetNodeTriads was returning 0 without looking into the OutGroupEdges. Fixed to go through and calculate if there are OutGroupEdges.
