    Added parallel connectivity filter · c59912e6
    Cory Quammen authored
    This new filter is a parallel version of vtkConnectivityFilter. It
    first computes the connectivity on each process, then ties together
    the different regions across process boundaries.
    
    * ScalarConnectivity mode is not supported.
    
    * Point and cell seeded connectivity is not supported.
    
    * The extraction modes VTK_EXTRACT_POINT_SEEDED_REGIONS,
      VTK_EXTRACT_CELL_SEEDED_REGIONS, and VTK_EXTRACT_SPECIFIED_REGIONS
        are not supported.
    
    Also added a test for vtkPConnectivityFilter that runs on 1 process
    and 4 processes.
