[vtkusers] Python FindClosestPoint

[Andy Bauer]

I think the issue is that you didn't create the actual point locator
object. It should look something like but possibly missing more stuff:
pl = vtk.vtkPointLocator()
pl.SetDataSet(dataset)
pl.FindClosestPoint(x, y, z)

There's a C++ example at
http://www.vtk.org/Wiki/VTK/Examples/Cxx/PolyData/PointLocator_Radius that
you can look at for reference.
