nektar reader plugin has points that should be merged but aren't
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The nektar reader plugin cell connectivity file format lists coordinates for each cell. Later on this points need to be merged because they'll be added in multiple times. vtkCleanUnstructuredGrid takes care of most of them but some of the coincident points aren't merged because they don't have the exact same value. This needs to be changed because otherwise there will be issues like the one in the uploaded file.
